When two boats share the same hull type — in this case both the Bennington 2575 QCW I/O 2013 and the Bennington 2875RLTDIO 2009 are pontoon designs with aluminum construction — 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?
The power gap is worth calling out. Rated to 430 hp, the Bennington 2575 QCW I/O 2013 has a 427-hp advantage over the Bennington 2875RLTDIO 2009's 3-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Bennington 2575 QCW I/O 2013 is rated for 13 passengers, while the Bennington 2875RLTDIO 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 QCW I/O 2013 could be the deciding factor.
One place where both boats are genuinely identical is tube construction: both run 3 aluminum tubes at 25" diameter. That shared spec means stability and buoyancy characteristics are closely matched — the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
Bottom line: Choose the Bennington 2575 QCW I/O 2013 if your priority is putting more people on the water — it handles 13 passengers and at 28,1 ft it has the deck room to back that rating up comfortably. The Bennington 2875RLTDIO 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.
