When two boats share the same hull type — in this case both the Rinker 310 EC 2010 and the Rinker Captiva 228 2011 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 310 EC 2010 measures 33,3 feet overall (2010), giving it roughly 10,6 additional feet of deck space compared to the Rinker Captiva 228 2011 at 22,7 feet (2011). Weight tells a clearer story for trailering families: the Rinker Captiva 228 2011 tips the scales at 5 031 lbs — 4 910 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 Captiva 228 2011 tops out at 320 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 Captiva 228 2011 carries 59 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 310 EC 2010 is rated for 10 passengers, while the Rinker Captiva 228 2011 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Rinker 310 EC 2010 could be the deciding factor.
