Grady-White Canyon 306 2011 vs Grady-White Canyon 336 2008 — Same Brand, Different Boat

The Grady-White Canyon 306 2011 vs Grady-White Canyon 336 2008 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Grady-White Canyon 306 2011 at 30,5 ft versus Grady-White Canyon 336 2008 at 33,0 ft. Weight tells a clearer story for trailering families: the Grady-White Canyon 306 2011 tips the scales at 695 lbs — 603 lbs more than the Grady-White Canyon 336 2008 at 92 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling — 700 hp for the Grady-White Canyon 306 2011 and 700 hp for the Grady-White Canyon 336 2008. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Grady-White Canyon 336 2008 carries 35 gallons versus 29 gallons in the Grady-White Canyon 306 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Grady-White Canyon 336 2008 is rated for 10 passengers, while the Grady-White Canyon 306 2011 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Grady-White Canyon 336 2008 could be the deciding factor.

Bottom line: Choose the Grady-White Canyon 336 2008 if your priority is putting more people on the water — it handles 10 passengers and at 33,0 ft it has the deck room to back that rating up comfortably. The Grady-White Canyon 306 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

The Grady-White Canyon 336 2008 is the longer of the two at 33,0 feet overall. The Grady-White Canyon 306 2011 comes in at 30,5 feet, making it roughly 2,5 ft shorter — a meaningful difference in deck room and overall on-water presence.

For trailering, the Grady-White Canyon 336 2008 has the edge at 92 lbs dry weight versus 695 lbs for the Grady-White Canyon 306 2011.

The Grady-White Canyon 306 2011 is Coast Guard rated for 9 passengers, while the Grady-White Canyon 336 2008 is certified for 10.

The Grady-White Canyon 336 2008 measures 139" wide, compared to 127" for the Grady-White Canyon 306 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
