Both the Four Winns V318 2009 and the Four Winns V435 2010 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 V435 2010 measures 43,5 feet overall (2010), giving it roughly 10,5 additional feet of deck space compared to the Four Winns V318 2009 at 33,0 feet (2009). Weight tells a clearer story for trailering families: the Four Winns V435 2010 tips the scales at 28 000 lbs - 15 900 lbs less than the Four Winns V318 2009 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.

The Four Winns V318 2009 carries a rated maximum of 300 hp. Engine data for the Four Winns V435 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 V435 2010 carries 300 gallons versus 170 gallons in the Four Winns V318 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 V435 2010 is rated for 16 passengers, while the Four Winns V318 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 V435 2010 could be the deciding factor.
