When two boats share the same hull type — in this case both the Rinker 340 EC 2010 and the Rinker Captiva 248 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 340 EC 2010 measures 35,7 feet overall (2010), giving it roughly 11,0 additional feet of deck space compared to the Rinker Captiva 248 2011 at 24,7 feet (2011). Weight tells a clearer story for trailering families: the Rinker Captiva 248 2011 tips the scales at 535 lbs — 394 lbs less than the Rinker 340 EC 2010 at 141 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 248 2011 tops out at 430 hp. Engine specs for the Rinker 340 EC 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Rinker 340 EC 2010 carries 168 gallons versus 75 gallons in the Rinker Captiva 248 2011. 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 340 EC 2010 is rated for 10 passengers, while the Rinker Captiva 248 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 340 EC 2010 could be the deciding factor.
