Supra Launch 21 V 2006 vs Supra Sunsport 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Supra Launch 21 V 2006 or the Supra Sunsport 2004?

For trailering, the Supra Launch 21 V 2006 has the edge at 34 lbs dry weight versus 305 lbs for the Supra Sunsport 2004. 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.

Q: What is the maximum horsepower rating for these boats?

The Supra Launch 21 V 2006 has a documented max rating of 340 hp. Engine specifications for the Supra Sunsport 2004 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.

Q: How many people can each boat hold?

The Supra Launch 21 V 2006 is Coast Guard rated for 13 passengers, while the Supra Sunsport 2004 is certified for 10. 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.

Q: Which boat is wider, and does it affect trailering?

The Supra Sunsport 2004 measures 95" wide, compared to 1" for the Supra Launch 21 V 2006. 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.

Q: Are the Supra Launch 21 V 2006 and Supra Sunsport 2004 from the same manufacturer?

Yes — both the Supra Launch 21 V 2006 and the Supra Sunsport 2004 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.

Detailed Evaluation & Buyer Recommendation

Supra Launch 21 V 2006 vs Supra Sunsport 2004 — Same Brand, Different Boat

The Supra Launch 21 V 2006 vs Supra Sunsport 2004 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.

The Supra Launch 21 V 2006 carries a rated maximum of 340 hp. Engine data for the Supra Sunsport 2004 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

For family outings this is probably the sharpest distinction between the two. The Supra Launch 21 V 2006 is rated for 13 passengers, while the Supra Sunsport 2004 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Supra Launch 21 V 2006 could be the deciding factor.

Bottom line: Choose the Supra Launch 21 V 2006 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 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
