When two boats share the same hull type — in this case both the Four Winns H310 2008 and the Four Winns H310SS 2010 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?

On paper these two are close siblings in the size department — Four Winns H310 2008 at 31,0 ft versus Four Winns H310SS 2010 at 31,3 ft. At 836 lbs and 836 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 320 hp, the Four Winns H310 2008 has a 317-hp advantage over the Four Winns H310SS 2010's 3-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 13 gal and 13 gal — so range won't be a tiebreaker here.

Both boats are rated for 14 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.
