Both the Rinker 310 EC 2010 and the Rinker 320 Express Cruiser 2009 are modified-V designs, both built in fibreglass, so 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 310 EC 2010 at 33,3 ft versus Rinker 320 Express Cruiser 2009 at 34,0 ft. Weight tells a clearer story for trailering families: the Rinker 320 Express Cruiser 2009 tips the scales at 12 360 lbs - 260 lbs less than the Rinker 310 EC 2010 at 12 100 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 are rated for 10 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
