When two boats share the same hull type — in this case both the Rinker 186 Captiva Bowrider 2010 and the Rinker Captiva 220 MTX CC 2011 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?

On paper these two are close siblings in the size department — Rinker 186 Captiva Bowrider 2010 at 18,8 ft versus Rinker Captiva 220 MTX CC 2011 at 21,0 ft. Weight tells a clearer story for trailering families: the Rinker 186 Captiva Bowrider 2010 tips the scales at 231 lbs — 196 lbs more 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.

The Rinker Captiva 220 MTX CC 2011 tops out at 300 hp. Engine specs for the Rinker 186 Captiva Bowrider 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Rinker Captiva 220 MTX CC 2011 carries 39 gallons versus 29 gallons in the Rinker 186 Captiva Bowrider 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 186 Captiva Bowrider 2010 is rated for 9 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 186 Captiva Bowrider 2010 could be the deciding factor.
