Bennington 20 SFX 2013 vs Bennington 2550 RSFB 2017 — Same Brand, Different Boat

The Bennington 20 SFX 2013 vs Bennington 2550 RSFB 2017 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 350 hp, the Bennington 2550 RSFB 2017 has a 280-hp advantage over the Bennington 20 SFX 2013's 70-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Bennington 2550 RSFB 2017 carries 48 gallons versus 21 gallons in the Bennington 20 SFX 2013. 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 Bennington 20 SFX 2013 is rated for 23 passengers, while the Bennington 2550 RSFB 2017 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 20 SFX 2013 could be the deciding factor.

Bottom line: Choose the Bennington 20 SFX 2013 if your priority is putting more people on the water — it handles 23 passengers and at 20,4 ft it has the deck room to back that rating up comfortably. The Bennington 2550 RSFB 2017 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

Bennington 20 SFX 2013 vs Bennington 2550 RSFB 2017 — Common Questions

Which is the larger boat — the Bennington 20 SFX 2013 or the Bennington 2550 RSFB 2017?
The Bennington 2550 RSFB 2017 is the longer of the two at 25,0 feet overall. The Bennington 20 SFX 2013 comes in at 20,4 feet, making it roughly 4,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Bennington 2550 RSFB 2017 is rated to a maximum of 350 hp, giving it the larger power ceiling. The Bennington 20 SFX 2013 tops out at 70 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.
How many people can each boat hold?
The Bennington 20 SFX 2013 is Coast Guard rated for 23 passengers, while the Bennington 2550 RSFB 2017 is certified for 7. 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 has the larger fuel tank — the Bennington 20 SFX 2013 or the Bennington 2550 RSFB 2017?
The Bennington 2550 RSFB 2017 has the bigger tank at 48 gallons, versus 21 gallons on the Bennington 20 SFX 2013. That 26-gallon difference translates to roughly 79–133 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Bennington 20 SFX 2013 and Bennington 2550 RSFB 2017 from the same manufacturer?
Yes — both the Bennington 20 SFX 2013 and the Bennington 2550 RSFB 2017 are built by Bennington. That means shared dealer networks, common parts availability, and consistent build quality across the line.
