Both the Supra Launch 21V 2011 and the Supra Launch 22V 2011 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 Launch 21V 2011 at 21,3 ft versus Supra Launch 22V 2011 at 22,5 ft. At 3 800 lbs and 3 800 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling - 325 hp for the Supra Launch 21V 2011 and 325 hp for the Supra Launch 22V 2011. 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. Both carry nearly identical fuel loads - 50 gal and 50 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Supra Launch 22V 2011 is rated for 15 passengers, while the Supra Launch 21V 2011 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Supra Launch 22V 2011 could be the deciding factor.
Bottom line: Choose the Supra Launch 22V 2011 if your priority is putting more people on the water - it handles 15 passengers and at 22,5 ft it has the deck room to back that rating up comfortably. The Supra Launch 21V 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.
