The Bennington 2575 RFS I/O 2004 vs Bennington 2875RLXIO 2009 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 2875RLXIO 2009 measures 28,0 feet overall (2009), giving it roughly 4,0 additional feet of deck space compared to the Bennington 2575 RFS I/O 2004 at 24,0 feet (2004). Weight tells a clearer story for trailering families: the Bennington 2875RLXIO 2009 tips the scales at 3 762 lbs — 3 515 lbs less than the Bennington 2575 RFS I/O 2004 at 247 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.
Both boats share a closely matched power ceiling — 2 hp for the Bennington 2575 RFS I/O 2004 and 3 hp for the Bennington 2875RLXIO 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
For family outings this is probably the sharpest distinction between the two. The Bennington 2575 RFS I/O 2004 is rated for 16 passengers, while the Bennington 2875RLXIO 2009 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 2575 RFS I/O 2004 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Bennington 2575 RFS I/O 2004 comes in at 124 lbs per hp versus 1254 lbs per hp for the Bennington 2875RLXIO 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 2575 RFS I/O 2004 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Bennington 2875RLXIO 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 2575 RFS I/O 2004 if your priority is putting more people on the water — it handles 16 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Bennington 2875RLXIO 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
