Our Take
The 336 Canyon represents Grady-White's most refined execution of the offshore center console formula. The SeaV2 hull isn't just marketing—it's a measurable performance advantage in rough water. I've run this boat in 4-to-5-foot seas off Hatteras, and the difference between the 336 and a comparable 35-footer with a flatter entry is night and day. The build quality is consistent with what you expect from Grady: through-bolted hardware, composite stringers, and a level of fit and finish that holds up after 500 hours of hard use.
This boat is for the angler who's past the "maybe I'll fish this weekend" phase and into the "I have a standing Saturday departure time" phase. It's not a family cruiser with fishing features bolted on. It's a fishing platform with enough comfort to make long runs tolerable. The lockable console with a real head and berth is a practical addition, not a selling point. You'll use it when you need it, but you're not buying this boat to overnight at anchor.
The market for the 336 is strong, and resale reflects that. Grady-White owners tend to be repeat buyers, and the brand's reputation for customer satisfaction isn't accidental. Maintenance costs are predictable if you stay on top of Yamaha service intervals. The Seakeeper 3 is worth the investment if you fish in following seas or spend time drifting—it's not a gimmick. Expect this boat to hold 70 to 75 percent of its value after three years, assuming you don't defer maintenance or run it into a sandbar. If you're comparing this against an Everglades or a Yellowfin, the Grady-White's ride quality and build consistency are the differentiators. It's not the flashiest boat in the class, but it's the one you'll still want to own in year five..

Frequently Asked Questions
How much fuel does the Grady-White Canyon 336 hold?
The Canyon 336 carries 361 gallons of fuel as standard, plus a 35-gallon freshwater tank. At its optimum cruise of 31.5 mph the triple Yamaha 350 package returns 1.27 miles per gallon.
Grady-White does not publish a range figure for this boat, and we will not invent one. What the published numbers support is straightforward arithmetic: 361 gallons at 1.27 mpg is roughly 458 statute miles of theoretical range, before you subtract the reserve any sensible offshore owner keeps. Treat that as a ceiling, not a plan.
Is the Grady-White Canyon 336 a good offshore fishing boat?
Yes — it is the most capable offshore boat of the four Grady-White models we review. It runs 33'6" on an 11'7" beam, carries 361 gallons of fuel, takes up to 1,050 horsepower, and sits on Grady-White's SeaV2® continuously variable-deadrise hull with 20 degrees of transom deadrise.
The beam is the part buyers underrate. An extra foot across compared with the Canyon 306 is what lets four or five anglers work a fish around the boat instead of shuffling out of each other's way, and it is the main reason to accept the extra weight and fuel burn.
Can you sleep on a Grady-White Canyon 336?
Not properly. The Canyon 336 has a cushioned berth forward inside the console, which is somewhere to get out of the sun or put a child down for an hour — it is not a cabin, and two adults will not spend a comfortable night in it.
The console also holds a lockable head with stand-up room, a shower, a sink, a VacuFlush head and a 10-gallon holding tank. If overnighting matters, the Freedom 345 is the boat in this size range with an actual cabin: a port stateroom with an electrically operated sliding berth, a bench seat and a closet, plus a separate enclosed head.
How fast is the Grady-White Canyon 336?
The Canyon 336 runs 58.8 mph at 5,950 RPM on triple Yamaha 350s, and 53.9 mph at 6,000 RPM on twin Yamaha XTO 450s. Optimum cruise on the triples is 31.5 mph at 3,400 RPM, burning 24.8 gallons an hour.
Grady-White publishes these in miles per hour, not knots. Note that the twin XTO 450 package cruises at 29.0 mph on 22.6 gph — slightly slower and slightly thriftier than the triples, and with one less engine to buy and service.
