When two boats share the same hull type — in this case both the Grady-White Canyon 306 2012 and the Grady-White Canyon 336 2012 are modified vee designs with fiberglass construction — 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?

On paper these two are close siblings in the size department — Grady-White Canyon 306 2012 at 30,5 ft versus Grady-White Canyon 336 2012 at 33,5 ft. Weight tells a clearer story for trailering families: the Grady-White Canyon 306 2012 tips the scales at 695 lbs — 603 lbs more than the Grady-White Canyon 336 2012 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 2012 and 700 hp for the Grady-White Canyon 336 2012. 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 2012 carries 35 gallons versus 29 gallons in the Grady-White Canyon 306 2012. 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 2012 is rated for 10 passengers, while the Grady-White Canyon 306 2012 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 2012 could be the deciding factor.
