The Supra Launch 21 V 2006 vs Supra Launch Gravity 24 SSV 2009 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Supra Launch 21 V 2006 at 21,0 ft versus Supra Launch Gravity 24 SSV 2009 at 24,0 ft. Weight tells a clearer story for trailering families: the Supra Launch Gravity 24 SSV 2009 tips the scales at 395 lbs — 361 lbs less than the Supra Launch 21 V 2006 at 34 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 21 V 2006 and 340 hp for the Supra Launch Gravity 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.
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 Launch 21 V 2006 caps at 13. 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.
Bottom line: Choose the Supra Launch Gravity 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 21 V 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
