When two boats share the same hull type — in this case both the Grady-White Marlin 300 2011 and the Grady-White Tournament 307 2010 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 Marlin 300 2011 at 32,6 ft versus Grady-White Tournament 307 2010 at 30,4 ft. Weight tells a clearer story for trailering families: the Grady-White Marlin 300 2011 tips the scales at 8 221 lbs — 7 436 lbs more than the Grady-White Tournament 307 2010 at 785 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 Marlin 300 2011 and 700 hp for the Grady-White Tournament 307 2010. 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 Tournament 307 2010 carries 206 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.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
