Supra Gravity 24 SSV 2006 vs Supra Launch 21 2005 — Same Brand, Different Boat

The Supra Gravity 24 SSV 2006 vs Supra Launch 21 2005 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 Gravity 24 SSV 2006 at 24,0 ft versus Supra Launch 21 2005 at 21,0 ft. Weight tells a clearer story for trailering families: the Supra Gravity 24 SSV 2006 tips the scales at 395 lbs — 363 lbs more than the Supra Launch 21 2005 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 Supra Gravity 24 SSV 2006 carries a rated maximum of 450 hp. Engine data for the Supra Launch 21 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

For family outings this is probably the sharpest distinction between the two. The Supra Gravity 24 SSV 2006 is rated for 16 passengers, while the Supra Launch 21 2005 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Supra Gravity 24 SSV 2006 could be the deciding factor.

Bottom line: Choose the Supra Gravity 24 SSV 2006 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 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.

Supra Gravity 24 SSV 2006 vs Supra Launch 21 2005 — Common Questions

Which is the larger boat — the Supra Gravity 24 SSV 2006 or the Supra Launch 21 2005?
The Supra Gravity 24 SSV 2006 is the longer of the two at 24,0 feet overall. The Supra Launch 21 2005 comes in at 21,0 feet, making it roughly 3,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Supra Gravity 24 SSV 2006 or the Supra Launch 21 2005?
For trailering, the Supra Launch 21 2005 has the edge at 32 lbs dry weight versus 395 lbs for the Supra Gravity 24 SSV 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
What is the maximum horsepower rating for these boats?
The Supra Gravity 24 SSV 2006 has a documented max rating of 450 hp. Engine specifications for the Supra Launch 21 2005 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Supra Gravity 24 SSV 2006 is Coast Guard rated for 16 passengers, while the Supra Launch 21 2005 is certified for 13. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Supra Gravity 24 SSV 2006 measures 102" wide, compared to 98" for the Supra Launch 21 2005. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Supra Gravity 24 SSV 2006 and Supra Launch 21 2005 from the same manufacturer?
Yes — both the Supra Gravity 24 SSV 2006 and the Supra Launch 21 2005 are built by Supra. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
