When two boats share the same hull type — in this case both the Supra Launch Gravity 24 SSV 2008 and the Supra Sunsport 20 V 2008 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 Supra Launch Gravity 24 SSV 2008 measures 24,0 feet overall (2008), giving it roughly 22,0 additional feet of deck space compared to the Supra Sunsport 20 V 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Supra Launch Gravity 24 SSV 2008 tips the scales at 395 lbs — 363 lbs more than the Supra Sunsport 20 V 2008 at 32 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 450 hp, the Supra Launch Gravity 24 SSV 2008 has a 110-hp advantage over the Supra Sunsport 20 V 2008's 340-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Supra Launch Gravity 24 SSV 2008 carries 52 gallons versus 4 gallons in the Supra Sunsport 20 V 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 Supra Launch Gravity 24 SSV 2008 is rated for 16 passengers, while the Supra Sunsport 20 V 2008 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Supra Launch Gravity 24 SSV 2008 could be the deciding factor.
