When two boats share the same hull type — in this case both the Supra Launch 21V 2010 and the Supra Launch 24 SSV 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?
On paper these two are close siblings in the size department — Supra Launch 21V 2010 at 21,3 ft versus Supra Launch 24 SSV 2009 at 24,0 ft. Weight tells a clearer story for trailering families: the Supra Launch 24 SSV 2009 tips the scales at 395 lbs — 357 lbs less than the Supra Launch 21V 2010 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 — 325 hp for the Supra Launch 21V 2010 and 325 hp for the Supra Launch 24 SSV 2009. 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. Both carry nearly identical fuel loads — 52 gal and 52 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Supra Launch 24 SSV 2009 is rated for 16 passengers, while the Supra Launch 21V 2010 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 24 SSV 2009 could be the deciding factor.
Bottom line: Choose the Supra Launch 24 SSV 2009 if your priority is putting more people on the water — it handles 16 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Supra Launch 21V 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.
