Bennington 185SL 2009 vs Bennington 2874 RLIO 2007 — Same Brand, Different Boat

The Bennington 185SL 2009 vs Bennington 2874 RLIO 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 2874 RLIO 2007 measures 28,0 feet overall (2007), giving it roughly 10,0 additional feet of deck space compared to the Bennington 185SL 2009 at 18,0 feet (2009). Weight tells a clearer story for trailering families: the Bennington 2874 RLIO 2007 tips the scales at 3 762 lbs — 2 151 lbs less than the Bennington 185SL 2009 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 425 hp, the Bennington 2874 RLIO 2007 has a 365-hp advantage over the Bennington 185SL 2009's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Bennington 185SL 2009 is rated for 23 passengers, while the Bennington 2874 RLIO 2007 caps at 17. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 185SL 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Bennington 2874 RLIO 2007 comes in at 9 lbs per hp versus 27 lbs per hp for the Bennington 185SL 2009. 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 2874 RLIO 2007 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Bennington 185SL 2009 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 185SL 2009 if your priority is putting more people on the water — it handles 23 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Bennington 2874 RLIO 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 17 that costs less to run day-to-day.

Bennington 185SL 2009 vs Bennington 2874 RLIO 2007 — Common Questions

Which is the larger boat — the Bennington 185SL 2009 or the Bennington 2874 RLIO 2007?
The Bennington 2874 RLIO 2007 is the longer of the two at 28,0 feet overall. The Bennington 185SL 2009 comes in at 18,0 feet, making it roughly 10,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Bennington 185SL 2009 or the Bennington 2874 RLIO 2007?
For trailering, the Bennington 185SL 2009 has the edge at 1 611 lbs dry weight versus 3 762 lbs for the Bennington 2874 RLIO 2007. 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 2874 RLIO 2007 is rated to a maximum of 425 hp, giving it the larger power ceiling. The Bennington 185SL 2009 tops out at 60 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 185SL 2009 is Coast Guard rated for 23 passengers, while the Bennington 2874 RLIO 2007 is certified for 17. 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 is wider, and does it affect trailering?
The Bennington 2874 RLIO 2007 measures 102" wide, compared to 96" for the Bennington 185SL 2009. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Bennington 185SL 2009 and Bennington 2874 RLIO 2007 from the same manufacturer?
Yes — both the Bennington 185SL 2009 and the Bennington 2874 RLIO 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.
