The Supra Comp 20 2007 vs Supra SA450 2013 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 SA450 2013 measures 22,5 feet overall (2013), giving it roughly 20,5 additional feet of deck space compared to the Supra Comp 20 2007 at 2,0 feet (2007). Weight tells a clearer story for trailering families: the Supra Comp 20 2007 tips the scales at 305 lbs — 262 lbs more than the Supra SA450 2013 at 43 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 450 hp, the Supra SA450 2013 has a 110-hp advantage over the Supra Comp 20 2007's 340-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 Comp 20 2007 carries 34 gallons versus 5 gallons in the Supra SA450 2013. 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 SA450 2013 is rated for 13 passengers, while the Supra Comp 20 2007 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Supra SA450 2013 could be the deciding factor.
Bottom line: Choose the Supra SA450 2013 if your priority is putting more people on the water — it handles 13 passengers and at 22,5 ft it has the deck room to back that rating up comfortably. The Supra Comp 20 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
