When two boats share the same hull type — in this case both the Bennington 1875GLi 2010 and the Bennington 2575 RLi 2011 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?

Size is the most obvious dividing line here. The Bennington 2575 RLi 2011 measures 27,1 feet overall (2011), giving it roughly 6,9 additional feet of deck space compared to the Bennington 1875GLi 2010 at 20,2 feet (2010). Weight tells a clearer story for trailering families: the Bennington 2575 RLi 2011 tips the scales at 3 223 lbs — 1 314 lbs less than the Bennington 1875GLi 2010 at 1 909 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 60 hp, the Bennington 1875GLi 2010 has a 35-hp advantage over the Bennington 2575 RLi 2011's 25-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 RLi 2011 carries 33 gallons versus 26 gallons in the Bennington 1875GLi 2010. 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 RLi 2011 is rated for 25 passengers, while the Bennington 1875GLi 2010 caps at 23. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 2575 RLi 2011 could be the deciding factor.
