The Supra Comp 20 2006 vs Supra Launch 20 2008 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 Comp 20 2006 at 20,0 ft versus Supra Launch 20 2008 at 20,0 ft. At 3 050 lbs and 3 050 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 - 340 hp for the Supra Comp 20 2006 and 340 hp for the Supra Launch 20 2008. 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.
For family outings this is probably the sharpest distinction between the two. The Supra Launch 20 2008 is rated for 10 passengers, while the Supra Comp 20 2006 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Supra Launch 20 2008 could be the deciding factor.
Bottom line: Choose the Supra Launch 20 2008 if your priority is putting more people on the water - it handles 10 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Supra Comp 20 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
