When two boats share the same hull type — in this case both the Supra Launch Gravity 24 SSV 2009 and the Supra Sunsport 21V 2012 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?

On paper these two are close siblings in the size department — Supra Launch Gravity 24 SSV 2009 at 24,0 ft versus Supra Sunsport 21V 2012 at 21,3 ft. Weight tells a clearer story for trailering families: the Supra Launch Gravity 24 SSV 2009 tips the scales at 395 lbs — 357 lbs more than the Supra Sunsport 21V 2012 at 38 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.

Both boats share a closely matched power ceiling — 340 hp for the Supra Launch Gravity 24 SSV 2009 and 325 hp for the Supra Sunsport 21V 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Supra Launch Gravity 24 SSV 2009 carries 52 gallons versus 5 gallons in the Supra Sunsport 21V 2012. 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 2009 is rated for 16 passengers, while the Supra Sunsport 21V 2012 caps at 14. 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 2009 could be the deciding factor.
