When two boats share the same hull type — in this case both the Rinker Captiva 220 MTX CC 2011 and the Rinker Express Cruiser 310 EC 2012 are deep 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 Express Cruiser 310 EC 2012 measures 33,3 feet overall (2012), giving it roughly 12,3 additional feet of deck space compared to the Rinker Captiva 220 MTX CC 2011 at 21,0 feet (2011). Weight tells a clearer story for trailering families: the Rinker Express Cruiser 310 EC 2012 tips the scales at 13 635 lbs — 13 600 lbs less than the Rinker Captiva 220 MTX CC 2011 at 35 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.

Both boats share a closely matched power ceiling — 300 hp for the Rinker Captiva 220 MTX CC 2011 and 300 hp for the Rinker Express Cruiser 310 EC 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Rinker Captiva 220 MTX CC 2011 carries 39 gallons versus 15 gallons in the Rinker Express Cruiser 310 EC 2012. 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 Express Cruiser 310 EC 2012 is rated for 10 passengers, while the Rinker Captiva 220 MTX CC 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 Express Cruiser 310 EC 2012 could be the deciding factor.
