Both the Supra Launch 20 2008 and the Supra Launch 20SSV 2009 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 20 2008 at 20,0 ft versus Supra Launch 20SSV 2009 at 20,0 ft. Weight tells a clearer story for trailering families: the Supra Launch 20SSV 2009 tips the scales at 3 200 lbs - 150 lbs less than the Supra Launch 20 2008 at 3 050 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.
Both boats share a closely matched power ceiling - 340 hp for the Supra Launch 20 2008 and 325 hp for the Supra Launch 20SSV 2009. 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. Fuel capacity breaks the other way: the Supra Launch 20SSV 2009 carries 40 gallons versus 34 gallons in the Supra Launch 20 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 10 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Supra Launch 20 2008 and Supra Launch 20SSV 2009 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
