When two boats share the same hull type — in this case both the Bennington 23SL3 I/O 2010 and the Bennington 2550 RSR 2013 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?

On paper these two are close siblings in the size department — Bennington 23SL3 I/O 2010 at 25,2 ft versus Bennington 2550 RSR 2013 at 27,1 ft. Weight tells a clearer story for trailering families: the Bennington 2550 RSR 2013 tips the scales at 3 298 lbs — 487 lbs less than the Bennington 23SL3 I/O 2010 at 2 811 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 23SL3 I/O 2010 has a 170-hp advantage over the Bennington 2550 RSR 2013'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 23SL3 I/O 2010 carries 62 gallons versus 23 gallons in the Bennington 2550 RSR 2013. 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 2550 RSR 2013 is rated for 25 passengers, while the Bennington 23SL3 I/O 2010 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 2550 RSR 2013 could be the deciding factor.
