When two boats share the same hull type — in this case both the Rinker 186 Captiva Bowrider 2010 and the Rinker Express Cruiser 310 2013 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 2013 measures 33,1 feet overall (2013), giving it roughly 14,3 additional feet of deck space compared to the Rinker 186 Captiva Bowrider 2010 at 18,8 feet (2010). Weight tells a clearer story for trailering families: the Rinker Express Cruiser 310 2013 tips the scales at 13 575 lbs — 13 344 lbs less than the Rinker 186 Captiva Bowrider 2010 at 231 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.

For family outings this is probably the sharpest distinction between the two. The Rinker Express Cruiser 310 2013 is rated for 10 passengers, while the Rinker 186 Captiva Bowrider 2010 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Rinker Express Cruiser 310 2013 could be the deciding factor.
