Both the Supra SA550 2013 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 SA550 2013 at 22,5 ft versus Supra Sunsport 22 V 2008 at 22,0 ft. Weight tells a clearer story for trailering families: the Supra SA550 2013 tips the scales at 4 300 lbs - 500 lbs more than the Supra Sunsport 22 V 2008 at 3 800 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 550 hp, the Supra SA550 2013 has a 100-hp advantage over the Supra Sunsport 22 V 2008's 450-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Supra SA550 2013 carries 50 gallons versus 40 gallons in the Supra Sunsport 22 V 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
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 SA550 2013 caps at 13. 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 SA550 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
