When two boats share the same hull type — in this case both the Four Winns H210SS 2008 and the Four Winns SL242 2009 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 SL242 2009 measures 24,0 feet overall (2009), giving it roughly 22,0 additional feet of deck space compared to the Four Winns H210SS 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Four Winns SL242 2009 tips the scales at 508 lbs — 190 lbs less than the Four Winns H210SS 2008 at 318 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 375 hp, the Four Winns SL242 2009 has a 55-hp advantage over the Four Winns H210SS 2008's 320-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 SL242 2009 carries 58 gallons versus 4 gallons in the Four Winns H210SS 2008. 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 SL242 2009 is rated for 12 passengers, while the Four Winns H210SS 2008 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 SL242 2009 could be the deciding factor.
