2020 Grady-White Canyon 456 Boat in Montauk, NY 11954 US

An impressive engineering achievement, the Canyon 456

took extreme sportfishing luxury to the highest level when

she was introduced in 2019. The semi-enclosed helm has four

electronically adjustable seats and with flip-up bolsters, and the

curved windscreen provides excellent sightlines over the bow.

Electric side windows and a large overhead hatch provide fresh

air, and the integrated hardtop includes an electric cockpit shade

that extends over the aft-facing seats. Fishing features include twin

35-gallon livewells at the transom corners, a port rigging station,

tackle storage compartments, washdowns, and ten rod holders. A

cockpit galley to starboard features a stainless-steel refrigerator,

trash compartment, and a grill. Below decks, the stylish cabin

has a standup head with shower, two outboard galleys, and a

convertible dinette forward. The 456 Canyon comes standard

with a Seakeeper gyro stabilizer, a bow thruster, and an autoleveling

trim control system to ensure stability. Among the largest

unsinkable boats of its kind, quad Yamaha 350s reach a top speed

of nearly 50 knots.

The folks at Grady-White tell us that they conceived and designed the new Canyon 456 to be a luxurious – “no-compromise” – sportfishing yacht with virtually every practical amenity built-in that they could imagine. With a 21-degree deadrise at the transom, a 14’ (4.27 m) beam, a fuel capacity of 616 gallons (2,332 L) and quad Yamaha 425 outboards, she is intended to go virtually anywhere in most conditions. The level of detail, built-in comfort, and innovation is noteworthy for a boat of this size. Belowdecks, she has a large, standup head, good-sized galley, and a convertible dinette that seats four and sleeps two. But all of that is just the tip of this iceberg.

The new Grady-White Canyon 456 made her debut at this year's Miami Boat Show. We think she is the best boat that Grady has ever built.

The Grady-White Canyon 456 was created for those looking for the top-of-the-line alternative to traditional sportfishing convertibles which cost several million dollars, usually require a paid captain and have annual maintenance costs that can easily go into six digits. It is also positioned for anglers wanting to move up to a sportfishing machine that is also a large, comfortable yacht but can still be easily handled. In the process, virtually every creature comfort that Grady’s engineers could imagine was baked into the boat.

The helm is fully-enclosed on three sides with the instrument and steering wheel offset to starboard. The companionway hatch is to port. The port and starboard side panels of the windshield slide open to allow fresh air to flow through on the good weather days.

Grady-White calls its helm a “Sea Command Center™” and has trademarked the term to emphasize both the care with which it was designed and the technology employed. The helm has four individual forward-facing seats that are each electronically adjustable, with flip-up bolsters to allow comfort while standing and flip-down armrests. The builder made them attractive and the multi-density foam substructure has been ergonomically designed to fit the human body and help people stay in their seats while being supportive and comfortable. The seat upholstery is two-tone and the bolsters are comfortable to lean on.

The captain’s seat is in the center to starboard and the wheel, compass, instruments, accessory switches and all controls are offset to starboard as they should be – rather than centered as we sometimes see that makes everything symmetrical but awkward.

Extremely comfortable seating is a hallmark of the Canyon 456 and nowhere is it more obvious than at the helm. Bolsters, footrests, armrests and air-conditioning are all part of the bargain.

Note that the hardtop (Grady calls it the AV2 T-top®) extends over the helm seats. Optional side curtains are available to button up the helm area for three-season boating. 16,000 BTUs of air conditioning are available and on chilly days, it can reverse cycle and pump out heat. Overhead there is a storage net for PFDs or other gear.

A curved one-pieced windscreen with minimum-sized mullions maximize sightlines forward. Vents port and starboard electrically open for fresh air when wanted, but the enclosed design will keep guests comfortable when a chill is in the air. Overhead there is an electrically actuated sunroof with screen and shade. There are blue and white T-top underside lights as well as white LED spreader lights facing fore and aft. The Fusion speakers seen above are part of a standard package of premium sound equipment.

CZone® digital switching technology enables one-touch control of onboard systems including power, electrical, lighting, heat and air conditioning — even the seacocks. This is a complex yet, intuitive system that puts nearly every function of the boat at the captain’s fingertips. We usually only see CZone systems on large motoryachts. A software application allows remote command of these functions from the captain’s smartphone.

Grady-White's sea chest is a raw-water reservoir that provides raw water for all systems livewells, generator, air conditioning, washdowns, and more. This is a remarkable system and one that we have never seen in this class of boat.

The helm also holds the Fusion stereo system controls for the bow and T-top speakers. A separate Fusion control head is located in the console cabin, and the company uses the latest Fusion Signature Series speakers to deliver the sound everywhere on the boat.

Air-conditioning vents in the dash panel and under the seats will give the captain and crew welcome cool air on steamy hot and humid days in the tropics.

The entire helm area is covered by a stylish T-top (AV2 T-top®), and a three-sided enclosure with an integrated wraparound, one-piece windshield. The forward mullions have been moved slightly back and kept narrow to maximize sightlines. Electric side windows and a large overhead hatch allow in plenty of fresh air when the heating or 16,000 BTU air conditioning system is not needed. The top includes a built-in SureShade® electronically retractable cockpit shade that extends over the aft-facing seats to keep guests there out of the sun and rain.

On the top are found LED spreader lights forward and aft. Top-of-the-line deluxe GEMLUX® carbon fiber outriggers are available. Underneath the top features LED lighting and a huge netted storage area. Ten rod holders here are fishing-ready. For extra convenience, this boat comes equipped with a remote-controlled anchor light on the T-top, making the transition from day to night as simple as a press of a button. Safety handrails are seamlessly built-in, just where needed.

Stereo System. Grady-White has installed the Fusion Signature series stereo system with AM/FM tuner, MP3 auxiliary audio connections/amplifier, Bluetooth remote, two subwoofers in the cockpit, two speakers in the bow and four speakers in the AV2 T-top at the helm. A separate Fusion stereo system in the cabin has its own subwoofer and two speakers.

With the addition of the optional canvas and Clear2Sea side curtains, the helm can be buttoned up for three-season boating. This option creates a tremendous amount of added utility for this yacht, which can really do anything and go almost anywhere adventuresome boaters would like.

The Canyon 456 is powered by four Yamaha 425-hp engines. Livewells are in the transom both port and starboard. They are 35 gallons (1,321 L) each with lights and full column distribution inlets, overboard drains and 1500 GPH (5,678 L) pumps. The black rectangle in the transom is a covered 24” screen to show the anglers' sonar and navigation data.

Hull Design. The Canyon 456 hull was designed by C. Raymond Hunt & Associates, the same firm that has designed all other Grady-White boats since the 1990s. Since Hunt invented and pioneered the deep-V hull design in the early 1960s, it is little surprise that this design firm knows as much as any, and probably much more, than most designers about the nuances of creating a hull that maximizes the comfort aspects of the deep-V concept, while at the same time making the hull as efficient and stable as possible. Grady-White has trademarked its proprietary hull design calling it the SeaV2® design, with a nod to its continuously variable vee — the science behind the exceptional ride, handling and performance of Grady-White hulls.

While not often discussed, the ride and handling characteristics of Grady-White boats are one of their most important features for safety and comfort.

The Numbers. We have not tested the Canyon 456, but we look forward to doing so. Of course, the folks at Grady-White and Yamaha have tested the boat. While they didn’t tell us how many people were aboard or the tankage levels during the test, they did say that the quad 425s were turning 16 3/8 x 21 XTO OS props and had a test weight of 31,650 lbs. (14,356 kg) — including persons, fuel, water, gear, engines and accessories. 

They reported a top speed of 58 mph at 6000 rpm, getting 0.4 mpg. Best cruise, they say, was found at 3500 rpm where the boat went 30.1 mph, getting 0.68 mpg.

Seakeeper. The Canyon 456 is equipped with a Seakeeper® 6 gyro stabilizer “to give an added element of control in the most extreme sea conditions,” according to Grady-White. In normal conditions, it dampens roll significantly. The Yamaha Helm Master® system with Set Point™ is also standard. This system used dual-antenna GPS to engage three primary control modes – Stay Point, Fish Point and Drift Point.

Trim Tabs. Also standard is the Zipwake® dynamic auto-leveling trim control system that controls both trim and balance, providing constant leveling in turns and when accelerating. It also ensures maximum capability. The Canyon 456 has a variable speed bow thruster standard, as well.

Generator. The Canyon 456 comes standard with a 12 kW diesel generator with a 30-gallon (114 L) fuel tank. The generator is required to operate the A/C and the Seakeeper systems primarily, as well as to produce an abundance of power for the rest of the boat. It is noteworthy that Grady-White decided not to install a gasoline generator, which would simplify fueling. The reason is that a diesel generator has a much, much lower carbon monoxide risk, greater longevity and less maintenance.

Other Equipment. An electrical bow thruster, 11-gallon (42 L) water heater. An anchor windlass is also installed as standard. With so much electrical equipment aboard, the Canyon 456 has 10 batteries and three battery chargers.

The cockpit and “Sea Command Center” console have about everything imaginable included. Note the stainless steel refrigerator, storage for Plano tackle boxes and drawers for other gear. The wide center seat, with bolster, for the angler on deck, three conditioning vents and a pull-out footrest. There is room for a fighting chair if wanted or the optional rod station.

We were impressed by the thought and engineering that has gone into the Canyon 456’s cockpit. The 14’ (4.27 m) beam allows the integration of the Sea Command Center's aft-facing fishing station, with dedicated air conditioning/heating vents and seating for three in high, dry, and exceedingly comfortable seats. The middle seat has a flip-up bolster that serves as a leaning bar. Tackle storage has room for six Plano boxes plus two additional gear drawers that slide from under the bolstered seating.

To port, forward of the seats is a sink under a swing-up counter that has many uses. The faucet wand raises and lowers and pulls out and can be used to wash off the removable cutting board above.

Behind the center aft-facing seat are three A/C vents to direct cool air on the three anglers or their mates.

Mini-Galley on Deck. Portside there is a sink with an adjustable pull-out faucet hose with spray nozzle. The starboard side has a refrigerator and grill, and both have swing-up cutting board for bait prep or dressing freshly caught fish. When in the down position, these cutting boards become a handy place for beverages or snacks, and the rails around them keep everything in place.

Two Side Doors. Aft port and starboard cockpit side doors are positioned for landing fish, for reboarding swimmers or scuba divers, and for boarding from a dock. There is a hot and cold freshwater shower mounted near the starboard-side door.

Twin livewells – that total 70 gallons (265 L) – are located in the transom area, port and starboard. Both livewells feed off of the sea chest and have a full column plenum distribution system that allows fresh raw-water to circulate from top to bottom. What sets them apart from many large center consoles is their size. Adjacent is the expansive aft refrigerated/freezer fishbox.

Transom Fishbox. In the center of the transom is a 459 quart insulated refrigerator/freezer fishbox – with lights – that is digitally controlled. Of course, it drains overboard. There are two partitions so that it can be made into three separate compartments to adjust for the catch of the day.

Side doors on each side of this boat make getting on and off at a dock easy. They are also ideal for hauling aboard fish, swimmers, or scuba divers.

Robust hinges and latch will keep the side doors in place. Note that all coamings have large bolsters.

Aft-Facing Seats. One of the most impressive aspects of the Canyon 456 is her functionality combined with luxury. Who has not trolled for hours, looking at the deep blue, watching for signs of curious game fish – and sitting on an ice cooler, fiberglass console, or seat with a straight back and not much padding? Grady-White has banished roughing it while fishing, with its impressive aft-facing raised seating. Raised to give better visibility, and thoroughly cushioned for comfort. Adding to the comfort are air-conditioning vents behind, and the SureShade awning overhead. The center seat has a bolster.

This is far better for trolling and then jumping to action – just one step away – when there is a strike, than the typical mezzanine seating on a battlewagon.

Show and Tell. On the interior transom bulkhead, facing the three occupants facing aft in trolling mode, is a 24" electronic display screen (dealer-installed) so the aft-facing crew can see the fish sounder, and -- depending on the sophistication of the sounder – anglers can even watch fish rising to the bait. It can also show the exact position of the last strike — all the information the cockpit crew needs.

More Equipment. The aft transom itself includes a brand-new high-volume overboard-draining scupper system, plus a Glendenning 35’, 50-Amp motorized retractable shore power cord. The Canyon 456 is also equipped with the Reverso® pre-programmed engine flushing system. This Grady shines at night at the dock with underwater LED lights. There is a hot and cold freshwater shower with a 20’ long Glendenning retractable hose that can cover the width of the 14’-wide cockpit.

There is handy storage for six rods under the aft gunwales and, just forward, additional lockable storage for four more.

Clearly, with such a large distance between the standing angler in the cockpit and fish, a strategy must be in place for landing a game fish and keeping it away from the engines and props. That is one reason why Grady-White has built in two side doors. It is also when the joystick comes in handy. When anglers bring fish closer to the boat, they will probably be fighting from one of the two stern quarters, rather than having the fish directly astern, battlewagon-style.

When the fish is played out, and the angler gets close to bringing the prey close to wire, then the captain will maneuver the boat with one side or the other facing the fish. With the large bolsters around the cockpit, the angler and mate will have plenty of support when leaning over the side, bringing the fish to wire and landing it.

Access to the belowdecks cabin is via a sliding hatch with screen, located just forward of the portside bridge seat. Once below, to port of the integrated cabin steps, is a cedar-lined locker. Large side windows provide ambient light to fill the interior space. Exotic wood, superb cabinetry, luxurious fabrics, and Corian® countertops make the cabin at the same time both elegant and cozy.

There is a 12,000 BTU reverse-cycle system dedicated to the cabin cooling and heating.

The Galley. Below the portside countertop is a full-size microwave drawer, and a six-bottle wine cooler. A stainless steel sink and cooktop are located amidships on the starboard counter, with a refrigerator below. Lighted glass shelves are above the counters on each side.

The cabin on the Canyon 456 is an oasis of tranquility and a refuge from the heat or rain topside. Note the cabinets above the Corian® counters and cooktop to starboard.

With nearby rod storage for those who eat and sleep fishing, the dining table serves double-duty as a sleeping platform with the addition of a fill-in cushion. The dinette seats four for dinner or cocktails and sleeps two. It is electrically actuated. A TV is on the forward bulkhead.

The galley has a two-burner glass stovetop and sink with refrigerator below. We like the cupholders next to the galley.

The head has full-standing headroom and is remarkably large, thanks to the boat’s 14’ (4.27 m) beam. There is a separate shower stall. The toilet is a VacuFlush and there is a 20 gallon (76 L) holding tank.

Even the shower stall can perform double-duty as rod storage. The teak grate is standard.

Opposite the mini galley is another counter for food prep with appliances below, with a flip-up panel, notched and bungeed, to hold idle tackle. Rod storage is all over the boat, both inside and outside. The teak sole is standard.

Convertible Dinette. Forward center, there's an electronically-controlled solid Sapele wood dining table inlaid with teak and brushed aluminum accents, with seating up to four. Simply electronically lower the table for a forward berth that sleeps two comfortably. Overhead, there is a screened hatch.

A 32" flatscreen television is centered on the forward bulkhead. There is retractable vertical storage for four rods, neatly set under the portside countertop, and hides away when not in use. Alongside the berth, port and starboard, are the innovative, patent-pending Integrated Rod Storage Slides™ securely stowing four more rods outboard.

Head Compartment. The head is to starboard and includes a lighted, mirrored glass cabinet over the stainless steel sink, and a shower with a classic teak grid deck. A clever, elegant hinged fiberglass door partitions off the shower area, keeping the rest of the compartment dry, and creates an additional locker for another four rods. This luxurious cabin hosts lockable storage for a total of 12 rods.

This bow is made for entertaining and sunning. When in fishing mode, the tables can be dropped down to form a platform. Noted the clean deck forwards, with a through-the-stem anchor and pop-up cleats.

On deck, forward of the cabin, the Canyon 456 provides an elegant lounge-and-leisure platform. Atop the trunk cabin, comfortable lounge cushions create a large space for sun worshippers. The bow seating area continues the theme of exceptional detail, comfort, and elegant style. There are two large plumbed, insulated boxes portside (43 and 123 quarts), and a huge 210-quart box starboard. Of course, they can be used as beverage coolers or storage.   

A touch of a button moves the two bow tables up and down. Huge, insulated self-draining bins are under the seats and can serve as fishboxes.

A rotating seat back allows the seats forward to be used chaise-style with guests facing forward. Note the fine upholstery job. Remember, this is a center console extraordinaire.

On the trunk cabin, there is a built-in sun pad with deluxe chaise seating fold-down armrests. Note the rail around the cushions.

Dining and Sunning. Atop the storage boxes, deeply cushioned seating complemented by three-way positioned stowable backrests surrounds two motorized semi-circular fiberglass tables. When the tables are in the down position, they can be covered with cushions for yet another lounging platform. One notable advantage of the semicircular tables is that they allow access all the way to the bow and windlass, and loungers need not move out of the way.

Anchor rode storage can handle up to 400’ of rode and 30’ of chain. The windlass has controls at the bow and the helm. If fishermen are sight-casting off the bow, remove the cushions, and — voilà! — there's a large, strong casting platform.

The new flagship Canyon 456 epitomizes Grady-White's legacy of 59 years of building quality boats for the toughest condition. Here's a superb fishing yacht, true to its purebred sportfishing heart and soul that takes luxury and versatility to a new dimension.

The bow is kept clean thanks to this recessed ground tackle arrangement. The anchor is through the stem and note the large cleat for the anchor rode at right, something that many builders are omitting but should not.

We can picture taking the new Canyon 456 to the Bahamas or even Down Island. She is a well-thought-out, luxury sport fishing boat perfect for the hardcore fisherman and his family.

Simply put, we think this is one of the most innovative and remarkable Grady-White boats ever built. The attention to needed – or wanted – functionality is breathtaking. The execution shows that Grady-White can go toe-to-toe with most semi-custom center console builders when it has the size boat, and the budget, to work with.

Our guess is that a number of the good ideas seen in the Canyon 456 will trickle down to some of Grady’s smaller boats, and the folks that don’t need this much boat will want to find some of the same attributes in smaller center consoles.

The Grady-White Canyon 456 isn’t the biggest mega-center-console on the sea, but it is one of the best built and equipped. It’s not unusual to see a boatbuilder stretch a line of boats, adding a longer keel and maybe spreading the beam to get more deck space between the gunwales, but the trouble with that technique is there are unforeseen consequences of simply blowing out the hull like a ­master bedroom expansion.

Grady-White’s plan for this boat was thoughtful and thoroughly vetted by the serious fishing and cruising experience of its design team, engineers, executives and outside consultants. And it showed on our test day, when the patented SeaV2 hull took us smoothly far offshore for swordfish. Together, they infused the deck and ­cabin ­below with extreme passenger comfort and style that is planned into the shape and cut of every bulkhead, cabinet and ceiling panel.

The cabin sleeps two in a large berth converted from the elegant in-laid sapele wood dinette table.

The galley is nicely appointed.

There’s an ample-size bathroom with a roomy shower.

This genius is most subtle yet important in the cabin below. Imagine a spacious cabin under the helm that will sleep two in a large berth converted from the elegant in-laid sapele wood dinette table. A space like that must be about 9 feet wide and built to support cabinetry without head-cracking overhead beams while ­retaining the ability to hold everything firmly in place as the boat speeds through seas at up to 58 mph. Grady-White’s design employs molded-in bulkheads and supports for galley, head and berth structures that also stiffen the cabin and the hull. Overhead, beams are concave, stiffening the ceiling while providing channels for the soft, recessed LED lighting. The entire design is so natural that you might describe it as organic.

After reviewing the generous galley and ample-size bathroom with a roomy shower (that has clever vertical rod-holder storage built in), our next stop was the helm station. There, three 17-inch Garmin displays are each capable of providing chart plotting, sonar imaging, engine and systems data, and C-Zone digital switching to coordinate the AC/DC systems. For the most used electrical mechanisms like navigation lights and bilge pumps, there are tactile on/off buttons too.

Three 17-inch Garmin screens display a wealth of information.

There is Yamaha’s Helm Master joystick control as well, and the steering is buttery-smooth thanks to a new first from Yamaha: electronic steering. Turning the helm offers digital input to the hydraulic steering mechanisms, and magnetic feedback gives the skipper comfortable resistance to turn the four 425 hp engines smoothly with control, precise enough that this 45-foot vessel handles like a Lexus. Given the aggressive nature of the propulsion system behind the 456, this proves critical. Further, as we deep-dropped swordfish baits 1,500 feet, the Helm Master system kept us on station with Yamaha’s Drift Point.

The Canyon 456 blends performance with plush amenities.

Four electronically controlled contoured bucket seats installed on a solid-fiberglass leaning-post structure are separated by foldaway armrests. Each have flip-up bolsters, and beneath the seats are fold-down footrests — another clever design point that lets each helmsman decide whether to sit or stand independently of the others. Because the crew capacity on the Canyon 456 is high, so is the cooler capacity with an electric refrigerator on the starboard-side of the mezzanine seating and a refrigerated ice box on the transom, flanked by two livewells. There’s a surprise hideaway electric grill above the starboard fridge.

Each bucket seat has flip-up bolsters, and beneath the seats are fold-down footrests

Grady’s AV2 hardtop design is also organic in nature, with curved, tempered glass and power sliding windows nested in its superstructure, and an electrically extending overhead shade to cover the cockpit aft.

Aft-facing seats behind the helm seats can comfortably accommodate three passengers, and tackle storage beneath the seats keep gear organized. The optional rod-storage station in the center of the cockpit held six rods, and with those we lost count of the total rod storage when we hit 50 between the gunwales, hardtop, and lockable stowage under the gunwales and below deck to complement the array.

Shoppers hunting for direct comparisons will find a fleet of 40-plus-foot-long center-consoles on the market, but we found none that match the Grady in length, beam and standard features. Everglades’ narrower 435 ($1,085,715 with quad ­Yamaha 425s) makes Grady’s standard teak treatment and refrigerated compartments optional. The HCB Siesta 42 breaks a cool $1 million with quad 425s too, but it is 2 feet narrower and 3 feet shorter than the Grady.

Cocktail tables are split with a walkway beneath.

The coup de gras in the anglers’ cockpit on the Canyon would have to be the 24-inch Garmin on the transom — centered facing the crew, offering them a clear view of what the captain sees on the command deck.

Grady-White’s engineers kept the sun seekers in mind too, adding a large forward lounge atop the cabin’s ceiling, and wraparound lounges surround the flared gunwales to the forepeak. Cocktail tables are split with a walkway beneath to give crew access to the windlass, if needed.

You can go bigger if you want a longer center-console, but you’d be hard-pressed to get a bolder, more capable center-console than the Canyon 456.

The Canyon 456 provides a smooth ride.

High Points

• Seakeeper 6 and ZipWake dynamic trim control are standard for keeping the ride smooth and the crew comfortable.

• Both port and starboard gunwale doors offer convenient choices aboard.

• Nested in the port and starboard berths are Grady’s patent-pending sapele wood rod-storage slides holding four rods.

Low Points

• Be sure to remove rods from the hardtop’s rocket launchers before deploying the power sunshade.

• Stepping up to the helm deck improves the view but can cause you to stub a toe.

Piloting Grady-White’s new flagship Canyon 456 is like driving a Platinum-package Ford F350 Power Stroke Diesel, like throttling the Orient Express, like flying a Learjet 85. At least that’s how I imagine it: The 456 is ­powerful and capacious while remaining sophisticated and plush.

I arrived in Morehead City, North Carolina, in late August to fish-trial the new Grady with a crew of eight, including two other boating writers. We had decided to try for daytime swordfish, based on a budding fishery that local captains have ­developed over the past two years.

We met pre-dawn at a nearby marina, where the 456 floated aglow, its LED cockpit and underwater lights bathing it in soothing blue. After stowing gear in the cavernous center-console cabin, we settled onto the aft-facing mezzanine bench (a misnomer since this flat expanse is well-cushioned) and into the four-across helm seats — all electrically adjustable fore and aft, and equipped with armrests, bolsters and footrests.

The helm unit includes an aft-facing air-conditioned bench, tackle drawers, an electrically actuated footrest, grill, refrigerator drawer and more.

Offshore Run
Our helmsman, Cameron Boltes, Grady’s ­property manager, idled us away from the dock using the Helm Master system tied into the quad Yamaha 425 XTO outboards. A light breeze cut the humidity as we cruised through Bogue Sound, meeting up with our photo boat for the 60-mile offshore run.

The 2- to 4-foot seas seemed like child’s play for this lengthy platform as we loped along at a leisurely 30 mph, turning 4,000 rpm and burning 60 gph. Boltes turned on the AC at the helm, which also pipes to the back of the mezzanine bench — something we quickly coveted, especially as the sun rose. (The 456 comes with a 12 kW diesel generator.)

With the autopilot set, the boat ran on cruise control. At the helm, we swapped fishing stories and scanned the horizon for signs of life. Rainstorms with low ceilings jockeyed around us, but when the sky brightened, the 1,300-foot depths resonated a deep purple-blue.

As Boltes throttled back, he engaged the standard Seakeeper 6 gyro ­stabilizer. While the 456 settled into a gentle sway, we could see our photo boat still bobbing.

The four helm chairs each electrically adjust fore and aft, and come with bolsters and armrests.

Capt. Patrick Shore, a local mate who has targeted these swordies, set up our one deep line, using a Shimano Tiagra 130 reel with a Hooker electric motor on a custom bent-butt rod to lower the strip bait and 10-pound sash weight. After studying the gauges, he calculated a 4½-knot current.

Shore says the first summer that captains found the swords, the fish were small — 60 to 100 pounds. Last summer, they caught a few in the 200- to 400-pound range. Most times, he says, he gets four to five bites a trip.

Boltes oriented the 456 using the Helm Master joystick and the Lewmar bow thruster, which he says helps keep the proud bow of this big girl better aligned. Once Shore dropped the bait, we power-drifted between 1,300- and 1,800-foot depths before repeating the process. In the meantime, I studied this vessel stem to stern.

Long List
Right up front, let me apologize for lacking enough space to fully describe this luxury vessel and its exhaustive list of standard features. Instead, I’ll tell you what impressed me most.

The 456’s deck remains level throughout the vessel, except at the helm, where there’s a slight step up. This makes moving fore and aft with a fish or with an armload of gear so very easy. It also elevates the captain’s line of sight, something short anglers like me appreciate, and it adds height to the interior cabin space (I measured it at 6 feet, 6 inches).

Crew can access the sliding cabin door from the helm deck. The door lies just to port of the helm face. Positioning the entry there frees the passageways yet takes nothing away from the helm layout; my tester featured three (optional) 17-inch Garmin displays, a C-Zone head unit, Yamaha Command Link Plus display, Fusion stereo, toggle switches, and a Zipwake Dynamic Boat Trim Control System.

Coaming pads rim the entire inside perimeter of the vessel, which comes with port and starboard boarding doors. That leaves the transom section completely reserved for an oversize 115-gallon fish box (the largest of four insulated, overboard-draining fish boxes) and two 35-gallon livewells with full-column distribution and sea chests for the pumps.

Built into the transom bulkhead: an innovative electronics display mount (a frame with a plexiglass front) that can accommodate up to a 24-inch screen for monitoring depth and ­location while in the cockpit!

I found rails and handholds ­everywhere. I moved from the helm seat to the mezzanine while underway and always had a good grasp on ­something metal.

Grady strategically located ­numerous gunwale rod holders, including four in the bow, as well as open and locking horizontal rod storage and vertical rod storage above- and belowdecks. My test boat also came with an optional cockpit rocket launcher.

On deck, I found a grill, tackle ­drawers, a hidden drink cooler (beneath the starboard mezzanine cushion), a sink, refrigerator drawer, trash bin, and storage for lines and cleaning supplies.

We had one serious bite during the day, but no hookups. Had I been fishing stand-up, I would have loved the prominent toe rails along each side of the aft deck. Grady also impressed me with its high-volume scuppers, sure to quickly drain away any water from the nonskid.

Exceptional Encounter
By midafternoon, we had to call it a day. I took the helm to get a feel for the 456, and found it highly responsive with easy throttles and smooth power steering. The automatic trim tabs keep the bow nearly level throughout acceleration.

Fully loaded, the 456 reached 30 mph in 10.5 seconds. The quads push the boat into the high 50s (Yamaha numbers show the boat tops out at 58 mph at 6,000 rpm). In turns port and starboard, speed bleeds off slightly. As far as close-­quarters maneuvering: The Helm Master joystick and the Lewmar bow thruster (both standard) make this as close to a self-driving boat as a captain can currently get.

All in all, this impressive, galloping center-console runs dry, and while the seas barely challenged the hull that day, whenever the 456 landed in a trough, it remained solid.

At the end of the day, I could ­officially call this Fish Trial an exceptional experience. This vessel is as powerful and capable as a sport-fisher yet handles like a sports car. Targeting swordfish, we put all our eggs in one basket, but I’d fish this boat for anything and deem the ­outcome a rousing success.

The builder's new flagship, a plush center console

By Capt. Dave Lear, Updated: April 20, 2019

During a 60-mile run for a day of swordfishing off Morehead City, North Carolina, the ­45-footer showed its mettle. The deepwater gladiators failed to cooperate; nevertheless, the Canyon proved the perfect platform for any offshore hunt. Boasting a 14-foot beam, it offers a roomy ­cockpit with port- and starboard-side doors large enough to slide a hefty ­tuna aboard. Four insulated fish boxes with overboard drain ­— a 123- and a 43-quart in the port bow, a 239-quart to starboard, and a 459-quart on the aft transom ­­complete with lighting and refrigerator/freezer with digital thermostat — afford substantial capacity to store the crew’s catch. Meanwhile, a 24-inch electronics display, integrated into the transom, enables quick sonar checks without leaving the cockpit.

Deluxe seats with flip-up bolsters, and arm- and footrests accommodate four at the helm.

Live-baiting enthusiasts will ­appreciate the twin 35-gallon insulated wells on the transom corners, both with full-column water circulation and overboard drains. Fresh- and ­raw-water washdowns let the crew rinse the tackle, and keep the deck and gunwales clean. The port rigging station features a sink with pullout faucet and stainless-­steel storage drawers. The opposite side of the aft-facing seat comes with tackle storage compartments, a cooler box and air-conditioning vents. Meanwhile, a cockpit galley to starboard features a stainless-steel refrigerator, trash compartment, and a grill for hot lunches.

Rod storage is extensive. A total of 10 holders are strategically spaced along the covering boards, while horizontal racks accommodate six more outfits. There are also two lockable rod pods and a six-rod rocket launcher on the hardtop, which is ­fully equipped with outrigger plates, LED spreader lights, electrical air vents, mesh storage, a sliding sunroof, and a SureShade retractable overhead shade.

Aft-facing seating complete with a rigging station, tackle storage and AC is the ideal spot to watch the spread.

The Sea Command Center — with its integrated systems — is fitting for a boat this size. Four electrically adjustable helm chairs with flip-back bolsters, footrests, and stylish, durable covering provide comfortable seating for long offshore jaunts. A forward molded lounge with armrests and drink holders accommodates larger crews.

The wraparound glass windshield offers excellent visibility while underway. The electronics panel at the helm is ample enough to flush-mount the largest displays, and a deluxe stereo system with multiple speakers is standard, along with the necessary USB port and power connections for mobile devices. The 16,000 Btu air conditioner keeps everyone aboard comfortable.

A port sliding door leads down to a bright, well-appointed cabin. Two outboard galleys come with Corian countertops, microwave, wine cooler, ­stainless-steel sink and stove cooktop, and elegant cabinetry provides ample storage for cook- and dining ware. A 12 kW diesel generator with 30-gallon ­fuel capacity, 80-gallon water tank, and 11-gallon hot-water heater are all standard issue. A full head with shower, and a convertible berth with adjustable table in the forepeak provide more than suitable accommodations for extended trips or afterhours on the rip, and a second AC unit — this one 12,000 Btu — keeps the cabin cool.

Twin removable tables enhance bow seating and lounging.

The 456 earns top marks for performance too. By the time we turned back toward shore, the sea breeze had built up, creating a quarterly chop off the port bow. Those conditions were easily overcome thanks to Grady-White’s SeaV2 hull, with its aggressive entry and the transition aft to a 21-degree transom deadrise. The ride was soft and true, aided by a Seakeeper 6 gyroscopic stabilizer and a ZipWake auto-­leveling trim system, both standard on the Canyon.

Quad Yamaha F425 four-strokes are the standard power setup for the 456, and they provide plenty of torque and top-end speed. In fact, the Grady hovered near 60 mph at wide-open throttle with a typical load.

The well-appointed and stylish cabin offers a welcome respite after a long day on the water.

To the delight of anglers who like trolling, the wake was clean and tight. Despite the boat’s size, it responded quickly to trim adjustment and course corrections with minimal exertion, thanks to the outboard’s ­integrated electronic steering. Meanwhile, the joystick control and the Yamahas multiengine vectoring made tight docking and maneuvering a piece of cake.

If you’re thinking about moving up in size for the enhanced range, performance and comfort, or downsizing to a boat you can run yourself and fish, the new Canyon 456, a super-size center-­console with a wealth of ­lavish ­appointments and ­dedicated fishing ­features, is bound to meet or ­surpass your expectations.

Impressively engineered with power, extreme comfort, and serious fishability.

The Grady-White Canyon 456 isn’t the biggest mega-center-console on the sea, but it is one of the best built and equipped. It’s not unusual to see a boatbuilder stretch a line of boats, adding a longer keel and maybe spreading the beam to get more deck space between the gunwales, but the trouble with that technique is there are unforeseen consequences of simply blowing out the hull like a ­master bedroom expansion.

LOA: 45’0″ | Beam: 14’0″ | Draft (max): 2’6″ | Displacement (approx.): 28,500 lb. | Transom Deadrise: 21 degrees | Bridge Clearance: 10’5″ | Fuel Capacity: 616 gal. | Max Horsepower: 1,700 | Available Power: Quad Yamaha outboards to 425 hp each | More Information: gradywhite.com Courtesy Grady-White

Grady-White’s plan for this boat was thoughtful and thoroughly vetted by the serious fishing and cruising experience of its design team, engineers, executives and outside consultants. And it showed on our test day, when the patented SeaV2 hull took us smoothly far offshore for swordfish. Together, they infused the deck and ­cabin ­below with extreme passenger comfort and style that is planned into the shape and cut of every bulkhead, cabinet and ceiling panel.

This genius is most subtle yet important in the cabin below. Imagine a spacious cabin under the helm that will sleep two in a large berth converted from the elegant in-laid sapele wood dinette table. A space like that must be about 9 feet wide and built to support cabinetry without head-cracking overhead beams while ­retaining the ability to hold everything firmly in place as the boat speeds through seas at up to 58 mph. Grady-White’s design employs molded-in bulkheads and supports for galley, head and berth structures that also stiffen the cabin and the hull. Overhead, beams are concave, stiffening the ceiling while providing channels for the soft, recessed LED lighting. The entire design is so natural that you might describe it as organic.

After reviewing the generous galley and ample-size bathroom with a roomy shower (that has clever vertical rod-holder storage built in), our next stop was the helm station. There, three 17-inch Garmin displays are each capable of providing chart plotting, sonar imaging, engine and systems data, and C-Zone digital switching to coordinate the AC/DC systems. For the most used electrical mechanisms like navigation lights and bilge pumps, there are tactile on/off buttons too.

Three 17-inch Garmin screens display a wealth of information. Courtesy Grady-White

There is Yamaha’s Helm Master joystick control as well, and the steering is buttery-smooth thanks to a new first from Yamaha: electronic steering. Turning the helm offers digital input to the hydraulic steering mechanisms, and magnetic feedback gives the skipper comfortable resistance to turn the four 425 hp engines smoothly with control, precise enough that this 45-foot vessel handles like a Lexus. Given the aggressive nature of the propulsion system behind the 456, this proves critical. Further, as we deep-dropped swordfish baits 1,500 feet, the Helm Master system kept us on station with Yamaha’s Drift Point.

Four electronically controlled contoured bucket seats installed on a solid-fiberglass leaning-post structure are separated by foldaway armrests. Each have flip-up bolsters, and beneath the seats are fold-down footrests — another clever design point that lets each helmsman decide whether to sit or stand independently of the others. Because the crew capacity on the Canyon 456 is high, so is the cooler capacity with an electric refrigerator on the starboard-side of the mezzanine seating and a refrigerated ice box on the transom, flanked by two livewells. There’s a surprise hideaway electric grill above the starboard fridge.

Grady’s AV2 hardtop design is also organic in nature, with curved, tempered glass and power sliding windows nested in its superstructure, and an electrically extending overhead shade to cover the cockpit aft.

Aft-facing seats behind the helm seats can comfortably accommodate three passengers, and tackle storage beneath the seats keep gear organized. The optional rod-storage station in the center of the cockpit held six rods, and with those we lost count of the total rod storage when we hit 50 between the gunwales, hardtop, and lockable stowage under the gunwales and below deck to complement the array.

The Grady-White Canyon 456 is the biggest Grady White center console ever built. If size matters when you’re looking at a new fishing boat, then this is one you’ll want to take an in-depth look at—starting with this First Look Video, which we shot at the Miami International Boat Show during its unveiling.
In this case, although we are talking about a Grady-White, we do use the term “fishing boat” a bit loosely. Yes, the Canyon 456 has all the features you need to bag everything from a minnow to a marlin. There’s a huge 459-quart fishbox with integrated freezer coils and a digitally controlled thermostat built into the transom, flanked by a pair of 35-gallon insulated livewells with full column water inlets. The back of the hard-top pipework has a full array of rocket launchers to complement the six flush rod holders in the cockpit and four more in the bow. The inwales are so dang long Grady includes not one but two sets of under-gunwale rodracks on both sides of the boat, which also have locking hatches that close over the aft end to protect your reels. There’s plenty of tackle stowage built into the mezzanine-style seating. And as expected, the cockpit is rather enormous.

But lest you imagine a rough-and-tumble fish-fighting arena, know that this cockpit is also designed to pamper. It has chilled air blasting from the outdoor air conditioning, right behind the triple aft-facing mezzanine-style seats and also at the helm station. While the mezzanine seating may be ideal for bait-watching, it’s also ideal for sunbathing. And we’d agree that the giant LCD screen mounted in the transom could be used for fish-hunting with the fishfinder, but it seems a lot more likely to be used for entertaining views of things like dredge-cams and other underwater video feeds. Fishing boat? Nah—the Grady-White Canyon 456 is really more of a center console yacht that you can fish from.

The Canyon 456 is one massive center console, and in truth is more yacht than boat.

To be a yacht, of course, you need accommodations. Never fear, there’s plenty of room for a serious cabin inside that huge center console. It has a forward dinette that converts into a berth, a fully-enclosed stand-up head with a separate shower stall, and a galley with a refrigerator, microwave oven, cook-top, and six-bottle wine chiller. The entire space is chilled, too, via a 12,00 Btu air-conditioning system that comes standard. The cabin also has a yacht-like feel, with a teak sole and a teak dinette table, wine glass racks over the galley, and integrated lighting in the overhead.

Gentrified though it may be, the cabin does not ignore the angler in you. It has multiple rod stowage areas built-in, each of which is quite clever and makes use of space in unexpected ways. To either side of the V-berth, there are racks for a pair of rigs as large as 30’s tucked under the side-decks. The would be a major pain in the butt to access there, accept that Grady-White came up with that utterly ingenious way of accessing the space that we saw in the video: grab the rack itself, pull inboard, and it slides out on tracks for easy access. A clip-down top holds the rods in place no matter how rough it gets, but can be popped free with one hand.

Four more rods can sit in vertical holders by the galley, where they’re secured in place with a slide-uot support. This is a bit less impressive than those forward racks but it’s an effective way of stowing rods, and there’s one more surprise in store. Duck into the head, swing out the door laying against the aft bulkhead (which serves as the divider between the commode and shower stall) and you’ll discover another set of four vertical holders in a spot where it didn’t seem possible to locate a darn thing. Added bonus: fire up the shower, and the stall acts as a post-fishing washdown closet for your gear.

Between the berth, head, and galley rodracks, there’s dedicated stowage for 12 full-sized offshore rigs in the cabin of the Canyon 456.
Up in the bow, more yacht-like features abound. As is true on most giant center consoles, the top of the console cabin supports a monstrous sunpad. It boasts a thickly-cushioned backrest, and fold-down arm rests. The bow is so utterly huge, however, that there’s still room for a full forward bow cockpit with wrap-around seating and a split-table dinette. As such the bow isn’t dedicated fishing territory by a long shot, and you wouldn’t want to station more than a pair of anglers forward of the console while drift fishing or casting. But it does offer plenty of relaxing and socializing space—space which any yacht needs, of course. And again, considering the boat’s sheer volume, we wonder if it will ever make much of a difference to all but the hardest-core anglers. After all, you can still find room for eight or 10 swinging rods. Will that ever fall short? We seriously doubt it.

Whether you’re more interested in the fishing aspects of the Canyon 456 or its yachty attitude, the brace of quadruple Yamaha F350 outboards lining the transom are sure to please. Cruise is in the mid 30’s and top-end hits 55 MPH, which is rather stellar for a boat of this size and weight. Better yet, at cruise the 365 gets better than 0.6 GPH. While that may not seem very efficient at first glance, remember that this is a 12-ton boat – unloaded. And this is about the same cruising fuel economy you’d commonly see from a twin diesel convertible or express sportfishing boat of this length, but with a whole lot more zip at top-end.

Another performance high-point will come clearly into focus when the seas get snotty. The Canyon 456 comes standard with a Seakeeper 6 gyroscopic stabilization system. We texted these units extensively while researching How Seakeeper Works: Gyroscopic Stabilization for Boats, and found that they reduced rocking and rolling by up to an amazing 90-percent. Add to that the standard ZipWake auto-leveling dynamic trim system, and you’ll soon discover that there’s no need to stow the stemware prior to making that long run home after a day of fishing.

After going through this boat stem to stern, we’re ready to make a claim almost as big as the Canyon 456 itself: this isn’t just the largest Grady-White ever built, it’s also the best. It somehow manages to provide the perks and pleasures of a luxury yacht, right alongside all the fishing features you need to bag a blue-water behemoth. It offers the performance of an outboard boat, with the efficiency you’d expect from a diesel inboard boat. And it has the accommodations of a cruiser, built into the foot-print of a center console.

The cabin in the Grady-White Canyon 456 is worthy of being called yacht-quality.
You want a true center console yacht? The search ends right here.

The revolutionary Zipwake® dynamic auto-leveling trim control system also assures maximum capability. This Canyon packs a variable speed bow thruster standard as well. The entire helm area is covered by a stylish, sophisticated, enclosed AV2 T-top TM with an integrated wraparound windshield for maximum visibility and protection. Electronic side windows and a large overhead hatch allow plenty of fresh air when the heating or air conditioning system is not needed. This top includes a built-in SureShade® electronically retractable cockpit shade and LED spreader lights forward and aft. Top-of-the-line deluxe GEMLUX® carbon fiber outriggers are available. The underneath of the top features digital lighting and a huge netted storage area–a Grady specialty. Ten rod holders here are fishing-ready, and four deluxe stereo speakers provide the soundtrack to any adventure. For extra convenience, this Canyon comes equipped with a remote-controlled anchor light on the T-top, making the transition from day to night as simple as a press of a button. Safety handrails are seamlessly built-in, just where you need them.

Few if any luxury sportfish builders can boast of a better “business end” of the cockpit than the engineers at Grady-White. The extra beam on this Canyon allows the integration of the Sea Command Center’s amazing aft-facing fishing station, with dedicated air conditioning/heating vents and seating for three in high, dry, and exceedingly comfortable seats. The middle seat sports a flip-up bolster that serves as a lean bar. Tackle storage is truly spacious, with room for six tackle boxes plus two additional gear drawers that slide from under the bolstered seating. Portside there is a sink with an adjustable pull-out faucet hose with a spray nozzle. The starboard side has an outdoor galley featuring a refrigerator and grill for those on-board celebrations of fresh-caught seafood, or just for snacks and hors d’oeuvres.

Aft port and starboard cockpit side doors are positioned perfectly for landing fish or boarding. Another useful feature is the hot and cold freshwater shower mounted near the starboard side door, ready for a quick rinse after a swim or dive, or to wash off your rods after a catch. There is handy storage for six rods under the aft gunwales and, just forward, additional lockable storage for four more. Twin livewells are located in the transom area port and starboard, adjacent to the expansive aft refrigerated/freezer fish box. This aft box comes with two partitions so it can be sectioned in three sizes, to adjust for your catch of the day. On the interior transom wall is a thoughtfully designed area to mount an up to 24″ electronic display screen so the aft facing crew can see navigation direction, fish sounder, and the exact position of the last strike—all the information a fish fighter needs. The aft transom itself includes a brand new high volume overboard draining scupper system, plus a Glendenning 35-foot, 50 amp motorized retractable shore power cord. The Canyon 456 is powered by quad Yamaha outboard engines and boasts the Reverso® pre-programmed engine flushing system to keep them running perfectly. This Grady shines at night with water level LED lights.

Access to the expansive console cabin is via a sliding door with screen, located just forward of the portside bridge seat. To port of the integrated cabin steps is a cedar-lined closet. Large side windows provide ample ambient light to fill the interior space. A dazzling combination of exotic wood, superb cabinetry, luxurious fabrics, and Corian® countertops greet the eye. Below the portside countertop is a full-size microwave drawer and a six-bottle wine cooler for entertaining. A stainless steel sink and a cooktop are located amidships on the starboard counter, with a refrigerator drawer below. Lighted glass shelves are above the counters on each side. Forward center, there’s an electronically controlled solid sapele wood dining table inlaid with teak and brushed aluminum accents, seating up to four. Simply lower the table for a forward berth that sleeps two comfortably. Overhead, the screened hatch offers plenty of fresh air and ocean breezes on demand. A 32″ flat screen television is centered on the forward bulkhead. Retractable vertical storage for four rods, neatly set under the portside countertop, hides away when not in use. Alongside the berth, port and starboard, are the innovative, patent-pending Integrated Rod Storage Slides™ securely stowing four more rods. The generous console head is starboard and includes a lighted, mirrored glass cabinet over the stainless steel sink, and a shower with a classic teak grid floor. A clever, elegant hinged fiberglass door partitions off the shower area, keeping the rest of the compartment dry, and creates an additional locker for another four rods. This luxurious cabin hosts lockable storage for a total of 12 rods.

On deck, forward of the cabin, the Canyon 456 proves it has a double life as an elegant lounge-and-leisure platform. Atop the forward cabin, very comfortable lounge cushions create an incomparable space for sun worshippers. The bow seating area continues the theme of exceptional detail, comfort, and elegant style. There are two large plumbed, insulated boxes portside (43 and 123 quarts), and a huge 210-quart box starboard. Atop the boxes, deeply cushioned seating complemented by three-way positioned stowable backrests surrounds two motorized semi-circular fiberglass tables. When the tables are in the down position, they can be covered with cushions for yet another lounging platform. One notable advantage of the semicircular tables is that they allow access all the way to the bow and windless, and loungers need not move out of the way! Anchor rode storage include up to 400 feet of rode and 30 feet of chain. Drop the plow anchor anywhere the crew wants to stop. If fishermen are sight casting off the bow, remove the cushions, and–voila!–there’s an ample, strong casting platform.

The company has been under private ownership by National Marine Manufacturers Association Hall of Fame member Eddie Smith since 1968. Grady-White Boats has been recognized for top-ranking excellence in customer satisfaction in every third-party study ever done in the marine industry including the 16th consecutive National Marine Manufacturers Association (NMMA) CSI Award for excellence in customer satisfaction awarded in February 2018.

Whether you want to fish for bigeye tuna or probe the edges of Baltimore Canyon for billfish and yellowfin, a boat like the Grady-White Canyon 456 is sure to turn your head. This is the biggest Grady-White ever built, and although it's a center console fishing boat it's also a true yacht. You'd like to set off for an epic adventure while overnighting at the canyons? On this boat, you'll do so while enjoying a level of luxury that most people don't even get to experience on dry land. Take a glance at this short video preview of the new Canyon 456, and you'll begin to get an idea of why we say this.

The view both inside and outside of the Grady-White's console cabin should make it quite clear that this boat is well thought-out and then some. Touches like the cabin rodholders and the 24-inch transom multi-function display are completely unique ideas that Grady dreamed up specifically for this model. And they aren't the only unusual perks found on this boat - not by a long shot. Take note of the dive doors in both sides, so whichever side the dock is on, you're assured easy entry and egress. Check out how the builder engineered in not one pair but two pairs of under-gunwale rodracks, with locking hatches that close over the reels to protect your gear from both weathering and theft. And as you look at the quadruple electrically adjusted helm seats with flip-up bolsters and flip-down arm rests, be sure to check out how each individual seat has its own flip-down footrest.

On the Grady-White Canyon 456, every passenger gets a comfortable place to sit.

Much to our dismay, the Canyon 456 was boxed in at the Miami International Boat Show when we first laid eyes on it, so we couldn't go for a sea trial. Major bummer. But Grady-White's initial tests have been completed, and the results look pretty dang sweet: cruising at 3700 rpm turns in a speed of 31.4 mph, while getting 0.65 mpg. Slam down the throttles and this monstrous fish-hunter breaks the 55 mph mark. Power comes courtesy of four Yamaha F350C outboard engines, swinging 15.25 x 19 SWS II SDS props.

Despite the fact that the 456 is so much larger than other Grady-Whites it shares the same C. Raymond Hunt Associates hull design, dubbed "Sea V2," which is a variable-degree hull that starts out sharp at the entry and then tapers down to 21-degrees of deadrise at the transom. If it ain't broke don't fix it - thousands of hulls and decades of rough-water experience have proven its effectiveness. A new twist to making the hull perform even better, however, is the addition of a Seakeeper gyro stabilization system. We've tested a number of Seakeeper-equipped boats and found a rather shocking roll reduction commonly in the neighborhood of 90 percent. Yes, you read that right - 90 percent. You can learn more about it in Tech it Out: Control the Rock 'n Roll, but we recognize that this claim is so extreme it's hard to take anyone's word for it. So rather than asking anyone to believe us on this point we'll just recommend spending some time on the Canyon 456, or any other Seakeeper-equipped boat, to find out for yourself. But believe this: you should prepare to have your mind blown.

Enough about the luxury, the performance, and all those other things that will be considered secondary to die-hard anglers like us. Just how well will the Canyon 456 live up to expectations on the fishing grounds?

The first thing we need to point out is that between the 10 rocket launchers lining the T-top and pipework, the eight flush-mount holders in the gunwales and transom, and the 22-foot Gemlux outriggers, you'll have no problem pulling a massive spread. Anglers who like to live line with spot or haul a school of peanut bunker will appreciate the pair of 35 gallon livewells, which are served by 1,500 gph pumps and full-column water inlets. And once you haul your catch aboard you'll have plenty of places to stow it, ranging from the 459-quart transom kill box (which has integrated freezer coils so you don't need to haul hundreds of pounds of ice), to the 210-, 123-, and 43 quart forward fishboxes in the bow. 

There is an angling downside to this arrangement, in that between the huge transom box and the four monster outboards, standing in the cockpit it feels like the props are a million miles away. All fish will have to be landed on the hip, and there will always be a moment of fear as large, uncontrollable fish are brought through the propeller-induced danger zone. This is, of course, an issue on many large center console fishboats. And beyond this we find it tough to find any valid criticism of the Canyon 456. Sure, its cost of around $1.2 mil will present a slight road bump to ownership for many of us. But Grady-White's reliably higher resale value as compared to virtually any competitor also means that in the long run, you probably won't suffer from the extreme devaluation common to many powerboats. Yes, one could also complain that packing the bow with a huge sunpad and the forward lounger does eat into fishing space. But truth be told there's so much sheer volume to begin with, we really don't feel like there's any penalty being paid.

Could there be a better way to hit the canyons, than on a Canyon 456? 

The bottom line? If you're looking for the ultimate in bluewater fishing machines that maximize luxury, the Canyon 456 belongs on your short list. And if you're lucky enough to get one after reading this, we have just one request: can we get an invite on the next overnighter at the canyons!? C'mon, puh-leeeeeze?
