When two boats share the same hull type — in this case both the Grady-White Canyon 366 2013 and the Grady-White Express 330 2013 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 366 2013 at 36,6 ft versus Grady-White Express 330 2013 at 35,8 ft. Weight tells a clearer story for trailering families: the Grady-White Canyon 366 2013 tips the scales at 1 285 lbs — 201 lbs more than the Grady-White Express 330 2013 at 1 084 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.

The power gap is worth calling out. Rated to 1 050 hp, the Grady-White Canyon 366 2013 has a 350-hp advantage over the Grady-White Express 330 2013's 700-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Grady-White Canyon 366 2013 carries 42 gallons versus 35 gallons in the Grady-White Express 330 2013. 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 366 2013 is rated for 11 passengers, while the Grady-White Express 330 2013 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Grady-White Canyon 366 2013 could be the deciding factor.
