Both the Bennington 24 SFi 2011 and the Bennington 2575 QCW I/O 2012 are pontoon designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Bennington 2575 QCW I/O 2012 measures 28,1 feet overall (2012), giving it roughly 4,3 additional feet of deck space compared to the Bennington 24 SFi 2011 at 23,8 feet (2011). Weight tells a clearer story for trailering families: the Bennington 2575 QCW I/O 2012 tips the scales at 4 032 lbs - 2 157 lbs less than the Bennington 24 SFi 2011 at 1 875 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 2575 QCW I/O 2012 has a 275-hp advantage over the Bennington 24 SFi 2011's 150-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 QCW I/O 2012 carries 62 gallons versus 24 gallons in the Bennington 24 SFi 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 13 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.
Bottom line: The Bennington 2575 QCW I/O 2012 at 28,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Bennington 24 SFi 2011 at 23,8 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.
