When two boats share the same hull type — in this case both the Rinker 320 Express Cruiser 2008 and the Rinker 350 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?

On paper these two are close siblings in the size department — Rinker 320 Express Cruiser 2008 at 34,0 ft versus Rinker 350 Express Cruiser 2008 at 37,0 ft. Weight tells a clearer story for trailering families: the Rinker 350 Express Cruiser 2008 tips the scales at 1 555 lbs — 319 lbs less than the Rinker 320 Express Cruiser 2008 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 375 hp, the Rinker 350 Express Cruiser 2008 has a 75-hp advantage over the Rinker 320 Express Cruiser 2008's 300-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 350 Express Cruiser 2008 carries 235 gallons versus 165 gallons in the Rinker 320 Express Cruiser 2008. 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 350 Express Cruiser 2008 is rated for 11 passengers, while the Rinker 320 Express Cruiser 2008 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Rinker 350 Express Cruiser 2008 could be the deciding factor.
