Bennington 18 SLX 2013 vs Bennington 2275 RLIO3 2007 — Same Brand, Different Boat

The Bennington 18 SLX 2013 vs Bennington 2275 RLIO3 2007 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.

Size is the most obvious dividing line here. The Bennington 2275 RLIO3 2007 measures 22,0 feet overall (2007), giving it roughly 3,6 additional feet of deck space compared to the Bennington 18 SLX 2013 at 18,4 feet (2013). Weight tells a clearer story for trailering families: the Bennington 18 SLX 2013 tips the scales at 1 663 lbs — 1 374 lbs more than the Bennington 2275 RLIO3 2007 at 289 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 Bennington 18 SLX 2013 carries a rated maximum of 50 hp. Engine data for the Bennington 2275 RLIO3 2007 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Bennington 2275 RLIO3 2007 carries 62 gallons versus 26 gallons in the Bennington 18 SLX 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 2275 RLIO3 2007 is rated for 12 passengers, while the Bennington 18 SLX 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 2275 RLIO3 2007 could be the deciding factor.

The Bennington 2275 RLIO3 2007 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Bennington 18 SLX 2013 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 2275 RLIO3 2007 if your priority is putting more people on the water — it handles 12 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Bennington 18 SLX 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

The Bennington 2275 RLIO3 2007 is the longer of the two at 22,0 feet overall. The Bennington 18 SLX 2013 comes in at 18,4 feet, making it roughly 3,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Bennington 18 SLX 2013 or the Bennington 2275 RLIO3 2007?
For trailering, the Bennington 2275 RLIO3 2007 has the edge at 289 lbs dry weight versus 1 663 lbs for the Bennington 18 SLX 2013. 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.
What is the maximum horsepower rating for these boats?
The Bennington 18 SLX 2013 has a documented max rating of 50 hp. Engine specifications for the Bennington 2275 RLIO3 2007 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Bennington 18 SLX 2013 is Coast Guard rated for 7 passengers, while the Bennington 2275 RLIO3 2007 is certified for 12. 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 18 SLX 2013 and Bennington 2275 RLIO3 2007 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.

The Bennington 2275 RLIO3 2007 has the bigger tank at 62 gallons, versus 26 gallons on the Bennington 18 SLX 2013. That 36-gallon difference translates to roughly 108–181 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes — both the Bennington 18 SLX 2013 and the Bennington 2275 RLIO3 2007 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.
