When two boats share the same hull type — in this case both the Four Winns V278 2009 and the Four Winns V475 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?

Size is the most obvious dividing line here. The Four Winns V475 2010 measures 49,3 feet overall (2010), giving it roughly 21,3 additional feet of deck space compared to the Four Winns V278 2009 at 28,0 feet (2009). Weight tells a clearer story for trailering families: the Four Winns V278 2009 tips the scales at 736 lbs — 733 lbs more than the Four Winns V475 2010 at 3 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 Four Winns V278 2009 carries a rated maximum of 375 hp. Engine data for the Four Winns V475 2010 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Four Winns V278 2009 carries 85 gallons versus 38 gallons in the Four Winns V475 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 Four Winns V475 2010 is rated for 18 passengers, while the Four Winns V278 2009 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Four Winns V475 2010 could be the deciding factor.
