The Bennington 1850 FS 2007 vs Bennington 2875 RLXIO 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 2875 RLXIO 2007 measures 28,0 feet overall (2007), giving it roughly 10,0 additional feet of deck space compared to the Bennington 1850 FS 2007 at 18,0 feet (2007). Weight tells a clearer story for trailering families: the Bennington 2875 RLXIO 2007 tips the scales at 3 762 lbs — 1 853 lbs less than the Bennington 1850 FS 2007 at 1 909 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 2875 RLXIO 2007 has a 365-hp advantage over the Bennington 1850 FS 2007's 60-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 2875 RLXIO 2007 carries 62 gallons versus 26 gallons in the Bennington 1850 FS 2007. 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 1850 FS 2007 is rated for 23 passengers, while the Bennington 2875 RLXIO 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 1850 FS 2007 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Bennington 2875 RLXIO 2007 comes in at 9 lbs per hp versus 32 lbs per hp for the Bennington 1850 FS 2007. 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.
Both are inflatable designs, which means they pack down for compact storage, can be carried in a bag, and are dramatically lighter than equivalent rigid hulls. The trade-off is setup time and the need to monitor tube pressure regularly. Tube diameter differs: 23 or 25 in on the Bennington 1850 FS 2007 vs 25 in on the Bennington 2875 RLXIO 2007 — larger tubes generally mean more buoyancy and a drier, more stable ride.
Bottom line: Choose the Bennington 1850 FS 2007 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 2875 RLXIO 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.
