The Supra Comp 20 2006 vs Supra Liquid Force Brostock Edition 24V 2010 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.
Size is the most obvious dividing line here. The Supra Liquid Force Brostock Edition 24V 2010 measures 24,0 feet overall (2010), giving it roughly 22,0 additional feet of deck space compared to the Supra Comp 20 2006 at 2,0 feet (2006). At 305 lbs and 395 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 325 hp for the Supra Liquid Force Brostock Edition 24V 2010. 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 Liquid Force Brostock Edition 24V 2010 is rated for 16 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 Liquid Force Brostock Edition 24V 2010 could be the deciding factor.
Bottom line: Choose the Supra Liquid Force Brostock Edition 24V 2010 if your priority is putting more people on the water — it handles 16 passengers and at 24,0 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.
