When two boats share the same hull type — in this case both the Grady-White Canyon 336 2009 and the Grady-White Marlin 300 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?

On paper these two are close siblings in the size department — Grady-White Canyon 336 2009 at 33,5 ft versus Grady-White Marlin 300 2011 at 32,6 ft. Weight tells a clearer story for trailering families: the Grady-White Marlin 300 2011 tips the scales at 8 221 lbs — 8 129 lbs less than the Grady-White Canyon 336 2009 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 336 2009 and 700 hp for the Grady-White Marlin 300 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 Canyon 336 2009 carries 35 gallons versus 3 gallons in the Grady-White Marlin 300 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 2009 is rated for 10 passengers, while the Grady-White Marlin 300 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 2009 could be the deciding factor.
