The Supra SA350 2013 vs Supra Sunsport 20 V 2006 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 SA350 2013 measures 22,5 feet overall (2013), giving it roughly 20,5 additional feet of deck space compared to the Supra Sunsport 20 V 2006 at 2,0 feet (2006). At 43 lbs and 32 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 — 345 hp for the Supra SA350 2013 and 340 hp for the Supra Sunsport 20 V 2006. 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 SA350 2013 is rated for 13 passengers, while the Supra Sunsport 20 V 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 SA350 2013 could be the deciding factor.
Bottom line: Choose the Supra SA350 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 Sunsport 20 V 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.
