Both the Grady-White Canyon 306 2011 and the Grady-White Freedom 335 2013 are modified-V designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Grady-White Freedom 335 2013 measures 33,6 feet overall (2013), giving it roughly 3,1 additional feet of deck space compared to the Grady-White Canyon 306 2011 at 30,5 feet (2011). Weight tells a clearer story for trailering families: the Grady-White Freedom 335 2013 tips the scales at 11 900 lbs - 4 950 lbs less than the Grady-White Canyon 306 2011 at 6 950 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 Freedom 335 2013. 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 Freedom 335 2013 carries 312 gallons versus 290 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 Freedom 335 2013 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 Freedom 335 2013 could be the deciding factor.
Bottom line: Choose the Grady-White Freedom 335 2013 if your priority is putting more people on the water - it handles 10 passengers and at 33,6 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.
