When two boats share the same hull type — in this case both the Four Winns H310 2012 and the Four Winns S215 SS 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 Four Winns H310 2012 measures 31,3 feet overall (2012), giving it roughly 10,0 additional feet of deck space compared to the Four Winns S215 SS 2013 at 21,3 feet (2013). Weight tells a clearer story for trailering families: the Four Winns H310 2012 tips the scales at 836 lbs — 411 lbs more than the Four Winns S215 SS 2013 at 425 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 Four Winns H310 2012 is rated for 14 passengers, while the Four Winns S215 SS 2013 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Four Winns H310 2012 could be the deciding factor.
