The Supra Sunsport 21V 2010 vs Supra Sunsport 24 V 2007 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 Sunsport 21V 2010 at 21,3 ft versus Supra Sunsport 24 V 2007 at 24,0 ft. Weight tells a clearer story for trailering families: the Supra Sunsport 24 V 2007 tips the scales at 395 lbs — 357 lbs less than the Supra Sunsport 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.
The power gap is worth calling out. Rated to 450 hp, the Supra Sunsport 24 V 2007 has a 125-hp advantage over the Supra Sunsport 21V 2010's 325-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. 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 Sunsport 24 V 2007 is rated for 16 passengers, while the Supra Sunsport 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 Sunsport 24 V 2007 could be the deciding factor.
Bottom line: Choose the Supra Sunsport 24 V 2007 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 Sunsport 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.
