Bennington 20 SLi 2011 vs Bennington 2275 GS 2006 — Same Brand, Different Boat

The Bennington 20 SLi 2011 vs Bennington 2275 GS 2006 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 — Bennington 20 SLi 2011 at 20,4 ft versus Bennington 2275 GS 2006 at 22,0 ft. Weight tells a clearer story for trailering families: the Bennington 2275 GS 2006 tips the scales at 2 335 lbs — 724 lbs less than the Bennington 20 SLi 2011 at 1 611 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 70 hp, the Bennington 20 SLi 2011 has a 45-hp advantage over the Bennington 2275 GS 2006's 25-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 24 gal and 26 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Bennington 20 SLi 2011 is rated for 23 passengers, while the Bennington 2275 GS 2006 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 20 SLi 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Bennington 20 SLi 2011 comes in at 23 lbs per hp versus 93 lbs per hp for the Bennington 2275 GS 2006. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

The Bennington 2275 GS 2006 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Bennington 20 SLi 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.

Bottom line: Choose the Bennington 20 SLi 2011 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 2275 GS 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.

Bennington 20 SLi 2011 vs Bennington 2275 GS 2006 — Common Questions

Which is the larger boat — the Bennington 20 SLi 2011 or the Bennington 2275 GS 2006?
The Bennington 2275 GS 2006 is the longer of the two at 22,0 feet overall. The Bennington 20 SLi 2011 comes in at 20,4 feet, making it roughly 1,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Bennington 20 SLi 2011 or the Bennington 2275 GS 2006?
For trailering, the Bennington 20 SLi 2011 has the edge at 1 611 lbs dry weight versus 2 335 lbs for the Bennington 2275 GS 2006. 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.
Which boat can handle a bigger outboard?
The Bennington 20 SLi 2011 is rated to a maximum of 70 hp, giving it the larger power ceiling. The Bennington 2275 GS 2006 tops out at 25 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 SLi 2011 is Coast Guard rated for 23 passengers, while the Bennington 2275 GS 2006 is certified for 14. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Bennington 20 SLi 2011 and Bennington 2275 GS 2006 share an 8 ft. 6 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Bennington 20 SLi 2011 and Bennington 2275 GS 2006?
Both boats carry similar fuel loads — 24 gallons and 26 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Bennington 20 SLi 2011 and Bennington 2275 GS 2006 from the same manufacturer?
Yes — both the Bennington 20 SLi 2011 and the Bennington 2275 GS 2006 are built by Bennington. 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.
