Both the Four Winns H310 2009 and the Four Winns V338 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?

Size is the most obvious dividing line here. The Four Winns V338 2009 measures 35,0 feet overall (2009), giving it roughly 4,0 additional feet of deck space compared to the Four Winns H310 2009 at 31,0 feet (2009). Weight tells a clearer story for trailering families: the Four Winns V338 2009 tips the scales at 13 600 lbs - 5 240 lbs less than the Four Winns H310 2009 at 8 360 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 power gap is worth calling out. Rated to 320 hp, the Four Winns H310 2009 has a 315-hp advantage over the Four Winns V338 2009's 5-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Four Winns V338 2009 carries 200 gallons versus 130 gallons in the Four Winns H310 2009. 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 Four Winns H310 2009 is rated for 14 passengers, while the Four Winns V338 2009 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Four Winns H310 2009 could be the deciding factor.
