Grady-White Canyon 306 Boats For Sale

The Grady-White Canyon 306 is a center console built around serious offshore fishing while keeping enough comfort to run as a family boat. It measures 30 feet 6 inches in length overall with a 10-foot-7-inch beam, drawing 21 inches and riding on the Grady-White CV2 hull, a continuously variable deadrise that measures 19.5 degrees at the transom and sharpens toward the bow. The wide beam is one of its strongest selling points, opening up cockpit space and giving stability at rest and at trolling speeds. Dry weight is listed at 6,950 pounds without engines, and fuel capacity runs to roughly 270 gallons, enough to make the boat's name literal: it is designed to run to the canyons 100 miles offshore and come home.

Power comes from twin Yamaha four-stroke outboards, available as twin 300s or twin 350s, with a maximum rating of 700 horsepower. With twin Yamaha V8 350s and Yamaha's 15.5-by-19-inch SDS props in calm water, the Canyon 306 reached a top speed of 58.1 mph at 6,000 RPM and planed in 2.7 seconds. Best cruise came at 3,000 RPM, where it ran 26.2 mph and burned 16.1 gph for a range of 424 miles with a 10 percent reserve. Owners running the twin 300s report fuel consumption around 1.7 to 1.8 mpg while cruising near 30 mph, with a 12-hour trip out of an inlet burning roughly 100 to 110 gallons.

The helm carries dual Garmin displays up to 16 inches, a stainless steel wheel with spinner knob, and a center compass with rocker switches grouped at the top of the dash. The optional Hellmaster package adds digital ignition control, joystick docking, and an information center that makes backing into a tight slip and walking the boat sideways far easier; some boats also add a bow thruster. Captain and companion seats feature diamond-stitch upholstery with Canyon 306 embroidery, flip-up bolsters, armrests, fore-and-aft adjustment, and fold-down footrests. The standard T-top mounts to the console rather than the deck to free up floor space, and an electric Sureshade extends cockpit cover at the push of a switch.

Fishing features are the heart of the layout. The cockpit holds a 47-gallon insulated raw-water live well with a light and full-column distribution, a bait prep station with freshwater sink, cutting board, and Plano tackle storage, plus a 304-quart insulated fish box with gas-assisted struts and a divider in the transom. The bow seats lift to reveal twin 150-quart insulated fish boxes that drain overboard. Rod stowage is generous, with eight rod holders spread across the cap rails to keep trolling lines from crossing, lockable under-gunnel rod storage, and dedicated holders at the rigging station. A thick transom door, a four-step boarding ladder, a tuna door, freshwater and saltwater wash downs, and a flip-out boarding step round out the working deck.

Belowdecks, the day head sits to starboard with a single magnetic door, 71 inches of headroom, a sink and faucet that doubles as a shower, a mirror, a port light for natural light, and an electric-flush marine head with a 10-gallon holding tank and pump-out. Build quality is a recurring theme, with high-grade stainless steel hardware and overboard drainage from the cockpit, fish boxes, live wells, and head to simplify cleanup. Options to weigh when buying include the convenience package with battery charger, dockside power, and galvanic isolator, the Hellmaster system, side-scan sonar, and the bow filler cushion that converts the forward seating into a sun pad. One Canyon 306 fitted with twin 300s was offered at $431,385; the model commands a premium in its class, but the engineering and finish are executed to a high standard throughout.
