Both the Supra Sunsport 20 V 2009 and the Supra Sunsport 22 V 2008 are modified-V designs, both built in fibreglass, so 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 Sunsport 20 V 2009 at 20,0 ft versus Supra Sunsport 22 V 2008 at 22,0 ft. Weight tells a clearer story for trailering families: the Supra Sunsport 22 V 2008 tips the scales at 3 800 lbs - 700 lbs less than the Supra Sunsport 20 V 2009 at 3 100 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 22 V 2008 has a 125-hp advantage over the Supra Sunsport 20 V 2009'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 - 40 gal and 40 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Supra Sunsport 22 V 2008 is rated for 15 passengers, while the Supra Sunsport 20 V 2009 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Supra Sunsport 22 V 2008 could be the deciding factor.
Bottom line: Choose the Supra Sunsport 22 V 2008 if your priority is putting more people on the water - it handles 15 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Supra Sunsport 20 V 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
