Bennington 2575 RFSIO 2006 vs Bennington 2575 RSi 2004 — Same Brand, Different Boat

The Bennington 2575 RFSIO 2006 vs Bennington 2575 RSi 2004 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 RFSIO 2006 at 25,0 ft versus Bennington 2575 RSi 2004 at 24,0 ft. Weight tells a clearer story for trailering families: the Bennington 2575 RSi 2004 tips the scales at 2 475 lbs — 2 116 lbs less than the Bennington 2575 RFSIO 2006 at 359 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 115 hp, the Bennington 2575 RSi 2004 has a 107-hp advantage over the Bennington 2575 RFSIO 2006's 8-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 17 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Bennington 2575 RSi 2004 comes in at 22 lbs per hp versus 45 lbs per hp for the Bennington 2575 RFSIO 2006. 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 RFSIO 2006 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Bennington 2575 RSi 2004 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.

Bottom line: Performance buyers should lean toward the Bennington 2575 RSi 2004 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Bennington 2575 RFSIO 2006 with its 8-hp rating is the more economical daily driver.

Bennington 2575 RFSIO 2006 vs Bennington 2575 RSi 2004 — Common Questions

Which is the larger boat — the Bennington 2575 RFSIO 2006 or the Bennington 2575 RSi 2004?
The Bennington 2575 RFSIO 2006 is the longer of the two at 25,0 feet overall. The Bennington 2575 RSi 2004 comes in at 24,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Bennington 2575 RFSIO 2006 or the Bennington 2575 RSi 2004?
For trailering, the Bennington 2575 RFSIO 2006 has the edge at 359 lbs dry weight versus 2 475 lbs for the Bennington 2575 RSi 2004. 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 2575 RSi 2004 is rated to a maximum of 115 hp, giving it the larger power ceiling. The Bennington 2575 RFSIO 2006 tops out at 8 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 2575 RFSIO 2006 is Coast Guard rated for 17 passengers, while the Bennington 2575 RSi 2004 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Bennington 2575 RFSIO 2006 and Bennington 2575 RSi 2004 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.
Are the Bennington 2575 RFSIO 2006 and Bennington 2575 RSi 2004 from the same manufacturer?
Yes — both the Bennington 2575 RFSIO 2006 and the Bennington 2575 RSi 2004 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.
