The Bennington 2575 RFS I/O 2004 vs Bennington 2575 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.
On paper these two are close siblings in the size department — Bennington 2575 RFS I/O 2004 at 24,0 ft versus Bennington 2575 RLIO 2007 at 25,0 ft. At 247 lbs and 315 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 425 hp, the Bennington 2575 RLIO 2007 has a 423-hp advantage over the Bennington 2575 RFS I/O 2004's 2-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 2575 RLIO 2007 carries 62 gallons versus 52 gallons in the Bennington 2575 RFS I/O 2004. 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 2575 RFS I/O 2004 is rated for 16 passengers, while the Bennington 2575 RLIO 2007 caps at 14. 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 RLIO 2007 comes in at 1 lbs per hp versus 124 lbs per hp for the Bennington 2575 RFS I/O 2004. 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.
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 2575 RLIO 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.
