When two boats share the same hull type — in this case both the Grady-White Express 305 2012 and the Grady-White Marlin 300 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 Express 305 2012 at 32,6 ft versus Grady-White Marlin 300 2012 at 32,6 ft. Weight tells a clearer story for trailering families: the Grady-White Marlin 300 2012 tips the scales at 8 221 lbs — 7 336 lbs less than the Grady-White Express 305 2012 at 885 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 Express 305 2012 and 700 hp for the Grady-White Marlin 300 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 Express 305 2012 carries 29 gallons versus 3 gallons in the Grady-White Marlin 300 2012. 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.
