When two boats share the same hull type — in this case both the Rinker 280 Express Crusier 2008 and the Rinker 400 Express Cruiser 2008 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?

Size is the most obvious dividing line here. The Rinker 400 Express Cruiser 2008 measures 42,0 feet overall (2008), giving it roughly 11,0 additional feet of deck space compared to the Rinker 280 Express Crusier 2008 at 31,0 feet (2008). Weight tells a clearer story for trailering families: the Rinker 400 Express Cruiser 2008 tips the scales at 1 968 lbs — 1 204 lbs less than the Rinker 280 Express Crusier 2008 at 764 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 2008 has a 50-hp advantage over the Rinker 280 Express Crusier 2008's 375-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 1 gal and 3 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Rinker 400 Express Cruiser 2008 is rated for 13 passengers, while the Rinker 280 Express Crusier 2008 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Rinker 400 Express Cruiser 2008 could be the deciding factor.
