When two boats share the same hull type — in this case both the Supra Sunsport 20V 2011 and the Supra Sunsport 242 2011 are modified vee designs with fiberglass construction — 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?

Size is the most obvious dividing line here. The Supra Sunsport 242 2011 measures 24,1 feet overall (2011), giving it roughly 3,4 additional feet of deck space compared to the Supra Sunsport 20V 2011 at 20,7 feet (2011). Weight tells a clearer story for trailering families: the Supra Sunsport 242 2011 tips the scales at 445 lbs — 413 lbs less than the Supra Sunsport 20V 2011 at 32 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 — 325 hp for the Supra Sunsport 20V 2011 and 325 hp for the Supra Sunsport 242 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. Fuel capacity breaks the other way: the Supra Sunsport 242 2011 carries 68 gallons versus 39 gallons in the Supra Sunsport 20V 2011. 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 Sunsport 242 2011 is rated for 17 passengers, while the Supra Sunsport 20V 2011 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Supra Sunsport 242 2011 could be the deciding factor.
