Supra Boats SL 2018 vs Supra Sunsport 20 V 2008 - Boat Spec Comparison

Q: Which is the larger boat — the Supra Boats SL 2018 or the Supra Sunsport 20 V 2008?

The Supra Boats SL 2018 is the longer of the two at 23,0 feet overall. The Supra Sunsport 20 V 2008 comes in at 2,0 feet, making it roughly 21,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The Supra Boats SL 2018 is rated to a maximum of 450 hp, giving it the larger power ceiling. The Supra Sunsport 20 V 2008 tops out at 340 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Supra Boats SL 2018 is Coast Guard rated for 7 passengers, while the Supra Sunsport 20 V 2008 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.

Q: Which boat has the larger fuel tank — the Supra Boats SL 2018 or the Supra Sunsport 20 V 2008?

The Supra Boats SL 2018 has the bigger tank at 73 gallons, versus 4 gallons on the Supra Sunsport 20 V 2008. That 69-gallon difference translates to roughly 207–345 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Supra Boats SL 2018 and Supra Sunsport 20 V 2008 from the same manufacturer?

Yes — both the Supra Boats SL 2018 and the Supra Sunsport 20 V 2008 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 Boats SL 2018 vs Supra Sunsport 20 V 2008 — Same Brand, Different Boat

The Supra Boats SL 2018 vs Supra Sunsport 20 V 2008 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 power gap is worth calling out. Rated to 450 hp, the Supra Boats SL 2018 has a 110-hp advantage over the Supra Sunsport 20 V 2008's 340-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Supra Boats SL 2018 carries 73 gallons versus 4 gallons in the Supra Sunsport 20 V 2008. 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 Boats SL 2018 is rated for 7 passengers, while the Supra Sunsport 20 V 2008 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Supra Boats SL 2018 could be the deciding factor.

Bottom line: Choose the Supra Boats SL 2018 if your priority is putting more people on the water — it handles 7 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Supra Sunsport 20 V 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
