When two boats share the same hull type — in this case both the Grady-White Canyon 306 2010 and the Grady-White Express 330 2011 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?

Size is the most obvious dividing line here. The Grady-White Express 330 2011 measures 35,8 feet overall (2011), giving it roughly 5,3 additional feet of deck space compared to the Grady-White Canyon 306 2010 at 30,5 feet (2010). Weight tells a clearer story for trailering families: the Grady-White Express 330 2011 tips the scales at 1 084 lbs — 389 lbs less than the Grady-White Canyon 306 2010 at 695 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 2010 and 700 hp for the Grady-White Express 330 2011. 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 Express 330 2011 carries 35 gallons versus 29 gallons in the Grady-White Canyon 306 2010. 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 Express 330 2011 is rated for 10 passengers, while the Grady-White Canyon 306 2010 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 Express 330 2011 could be the deciding factor.
