Supra Launch 21 2005 vs Supra Sunsport 20V 2011 — Same Brand, Different Boat

The Supra Launch 21 2005 vs Supra Sunsport 20V 2011 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 Launch 21 2005 at 21,0 ft versus Supra Sunsport 20V 2011 at 20,7 ft. At 32 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.

The Supra Sunsport 20V 2011 tops out at 325 hp. Engine specs for the Supra Launch 21 2005 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 36 gal and 39 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Supra Launch 21 2005 is rated for 13 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 Launch 21 2005 could be the deciding factor.

Bottom line: Choose the Supra Launch 21 2005 if your priority is putting more people on the water — it handles 13 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Supra Sunsport 20V 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.

Supra Launch 21 2005 vs Supra Sunsport 20V 2011 — Common Questions

Which is the larger boat — the Supra Launch 21 2005 or the Supra Sunsport 20V 2011?
The Supra Launch 21 2005 is the longer of the two at 21,0 feet overall. The Supra Sunsport 20V 2011 comes in at 20,7 feet, making it roughly 0,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Supra Launch 21 2005 or the Supra Sunsport 20V 2011?
For trailering, the Supra Sunsport 20V 2011 has the edge at 32 lbs dry weight versus 32 lbs for the Supra Launch 21 2005. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
What is the maximum horsepower rating for these boats?
The Supra Sunsport 20V 2011 has a documented max rating of 325 hp. Engine specifications for the Supra Launch 21 2005 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Supra Launch 21 2005 is Coast Guard rated for 13 passengers, while the Supra Sunsport 20V 2011 is certified for 1. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Supra Launch 21 2005 measures 98" wide, compared to 95" for the Supra Sunsport 20V 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Supra Launch 21 2005 or the Supra Sunsport 20V 2011?
The Supra Sunsport 20V 2011 has the bigger tank at 39 gallons, versus 36 gallons on the Supra Launch 21 2005. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Supra Launch 21 2005 and Supra Sunsport 20V 2011 from the same manufacturer?
Yes — both the Supra Launch 21 2005 and the Supra Sunsport 20V 2011 are built by Supra. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
