Detailed Evaluation & Buyer Recommendation

Supra Boats SL 2018 vs Supra Launch SS 2004 — Same Brand, Different Boat

The Supra Boats SL 2018 vs Supra Launch SS 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 Boats SL 2018 carries a rated maximum of 450 hp. Engine data for the Supra Launch SS 2004 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Supra Boats SL 2018 carries 73 gallons versus 34 gallons in the Supra Launch SS 2004. 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 Launch SS 2004 is rated for 10 passengers, while the Supra Boats SL 2018 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Supra Launch SS 2004 could be the deciding factor.

The Supra Boats SL 2018 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
