The Grady-White Express 330 2012 vs Grady-White Marlin 300 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Grady-White Express 330 2012 measures 35,8 feet overall (2012), giving it roughly 32,8 additional feet of deck space compared to the Grady-White Marlin 300 2007 at 3,0 feet (2007). Weight tells a clearer story for trailering families: the Grady-White Marlin 300 2007 tips the scales at 8 221 lbs — 7 137 lbs less than the Grady-White Express 330 2012 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 700 hp, the Grady-White Express 330 2012 has a 100-hp advantage over the Grady-White Marlin 300 2007's 600-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 Marlin 300 2007 carries 306 gallons versus 35 gallons in the Grady-White Express 330 2012. 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 2012 is rated for 10 passengers, while the Grady-White Marlin 300 2007 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 2012 could be the deciding factor.
