When two boats share the same hull type — in this case both the Rinker 310 EC 2010 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?

Size is the most obvious dividing line here. The Rinker 350 Express Cruiser 2008 measures 37,0 feet overall (2008), giving it roughly 3,8 additional feet of deck space compared to the Rinker 310 EC 2010 at 33,3 feet (2010). Weight tells a clearer story for trailering families: the Rinker 350 Express Cruiser 2008 tips the scales at 1 555 lbs — 1 434 lbs less than the Rinker 310 EC 2010 at 121 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 Rinker 350 Express Cruiser 2008 tops out at 375 hp. Engine specs for the Rinker 310 EC 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Rinker 350 Express Cruiser 2008 carries 235 gallons versus 15 gallons in the Rinker 310 EC 2010. 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 310 EC 2010 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.
