The Bennington 2575 RL I/O 2004 vs Bennington 2874 RCW I/O 2011 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 RCW I/O 2011 measures 31,1 feet overall (2011), giving it roughly 7,1 additional feet of deck space compared to the Bennington 2575 RL I/O 2004 at 24,0 feet (2004). Weight tells a clearer story for trailering families: the Bennington 2874 RCW I/O 2011 tips the scales at 4 262 lbs — 4 015 lbs less than the Bennington 2575 RL 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.
The power gap is worth calling out. Rated to 320 hp, the Bennington 2874 RCW I/O 2011 has a 318-hp advantage over the Bennington 2575 RL 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 2874 RCW I/O 2011 carries 62 gallons versus 52 gallons in the Bennington 2575 RL I/O 2004. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 16 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 2874 RCW I/O 2011 comes in at 13 lbs per hp versus 124 lbs per hp for the Bennington 2575 RL 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.
The Bennington 2575 RL 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 2874 RCW I/O 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The Bennington 2874 RCW I/O 2011 at 31,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Bennington 2575 RL I/O 2004 at 24,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
