Grady-White Canyon 306: BoatTEST Review
Overview
The Grady White Canyon 306 is a versatile 30-foot, 6-inch sport fishing boat designed to combine rugged offshore capability with comfortable family cruising accommodations. With a beam of 10 feet, 7 inches and a CV2 hull design, the Canyon 306 is engineered to provide a stable and smooth ride in choppy conditions at high speeds while maintaining stability at trolling speeds. Its design allows for safe trips to offshore canyons 100 miles or more from shore, making it suitable for serious fishing excursions as well as social and family outings.
Exterior Design and Deck Layout
The bow area of the Canyon 306 features walk-up access to the anchor locker, windlass, and controls, all set on a flush, non-skid surface. Two pull-up cleats and a navigation light are positioned forward, with a flush-mounted hatch for the windlass. Safety latches, cleats, and foot controls are conveniently located outside the starboard side, with additional windlass controls at the helm. The bow seating includes padded seats with bolsters, grab rails, cup holders, and optional adjustable backrests, creating a comfortable space for family or guests. The footwell can be filled with a cushion to convert into a sun pad or fishing platform. Beneath the seats, two 150-quart insulated fish boxes with gas-assisted lids drain overboard for easy maintenance. Freshwater and raw water hookups are located starboard and port respectively, and speakers are integrated into the gunnels on both sides.
Center Console and Helm Features
The center console includes a forward-facing molded seat and is protected by a full-height, scratch-resistant acrylic windshield equipped with a wiper and fresh water washdown. The standard T-top is supported by aluminum anchors integrated into the console, maximizing deck space and eliminating tripping hazards. It includes overhead handholds, lighting, speakers, an electronics box, and netted storage. To starboard of the console is entry to a day head featuring 71 inches of headroom, teak-lined decking, a marine electric flush head with a 10-gallon holding tank, a sink with a faucet that doubles as a shower, storage compartments, recessed lighting, and a port light.
Fishing and Utility Features
The helm is equipped with standard hydraulic trim tabs with indicators, and the test boat included optional Garmin autopilot, fish-finding electronics, engine readouts, and a well-organized dash with rocker switches and a centrally located compass. Optional packages include a convenience package with battery charger and dockside power with galvanic isolator, and a Helm Master package that adds ignition control, joystick docking, and a digital information center, greatly enhancing maneuverability. The helm seating features adjustable captain and companion seats with flip-up bolsters and armrests, storage beneath, and footrests. Behind the helm is a 47-gallon insulated raw water live well with lighting and overboard drainage, alongside a fresh water sink with a pull-out faucet and lockable storage stocked with tackle trays. Rod storage is abundant, with dedicated compartments in the gunnels, horizontal rod lockers with lockable latches, and multiple stainless steel rod holders integrated into the cap rails. Additional comfort and security are provided by tow rails and bolsters.
Cockpit and Transom
The cockpit features a large fold-out bench seat along the transom, pop-up cleats, a cutting board, and a 304-cord fish box with gas-assisted struts and locking latches. Fresh water washdown and a 30-amp shore power connection are located to starboard, along with engine flush mounts. The thick transom door with a heavy-duty latch provides access to the swim platform, which incorporates an aft reboarding ladder and serves as part of the integrated outboard mounting system. Four cockpit drains ensure efficient water drainage overboard. A flip-out step on the port quarter doubles as a seat, with battery switches and a raw water washdown hose nearby.
Power and Performance
The Canyon 306 offers three Yamaha four-stroke outboard engine options, with a maximum combined output of 700 horsepower. The test boat was powered by twin Yamaha V8 350s equipped with 15.5-inch diameter by 19-inch pitch SDS series propellers. Without engines, the boat's dry weight is 6,950 pounds; with two people aboard and 145 gallons of fuel, the test weight was 9,780 pounds. Performance testing in near-calm conditions recorded a top speed of 58.1 miles per hour at 6,000 RPM. The best cruising speed was 26.2 miles per hour at 3,000 RPM, burning 16.1 gallons per hour, resulting in a range of 424 miles with a 10% fuel reserve. Acceleration times included 2.7 seconds to plane, 4.6 seconds to 20 knots, 6.5 seconds to 30 knots, 10.1 seconds to 40 knots, and 15.1 seconds to 50 knots. The optional Helm Master system significantly improved maneuverability, especially during docking, allowing for precise joystick control including sideways movement.
Conclusion
The Grady White Canyon 306 stands out as a well-built, thoughtfully designed sport fishing boat that also accommodates family cruising and entertaining. Its combination of rugged offshore capability, comfortable accommodations, and advanced features such as the Helm Master system make it a top contender in its class. While it carries a higher price point, the quality of construction and attention to detail justify the investment. Overall, the Canyon 306 offers a versatile and reliable platform for both serious anglers and recreational boaters.
