The Rinker 320 Express Cruiser 2006 vs Rinker 400 Express Cruiser 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 Rinker 400 Express Cruiser 2007 measures 42,0 feet overall (2007), giving it roughly 9,0 additional feet of deck space compared to the Rinker 320 Express Cruiser 2006 at 33,0 feet (2006). Weight tells a clearer story for trailering families: the Rinker 400 Express Cruiser 2007 tips the scales at 1 968 lbs — 732 lbs less than the Rinker 320 Express Cruiser 2006 at 1 236 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 425 hp, the Rinker 400 Express Cruiser 2007 has a 145-hp advantage over the Rinker 320 Express Cruiser 2006's 280-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Rinker 320 Express Cruiser 2006 carries 165 gallons versus 3 gallons in the Rinker 400 Express Cruiser 2007. 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 Rinker 400 Express Cruiser 2007 is rated for 13 passengers, while the Rinker 320 Express Cruiser 2006 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Rinker 400 Express Cruiser 2007 could be the deciding factor.
