When two boats share the same hull type — in this case both the Bennington 2250 GBR 2012 and the Bennington 25 SL I/O 2012 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 2250 GBR 2012 at 24,1 ft versus Bennington 25 SL I/O 2012 at 24,3 ft. Weight tells a clearer story for trailering families: the Bennington 25 SL I/O 2012 tips the scales at 3 099 lbs — 375 lbs less than the Bennington 2250 GBR 2012 at 2 724 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 25 SL I/O 2012 has a 295-hp advantage over the Bennington 2250 GBR 2012'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 25 SL I/O 2012 carries 62 gallons versus 26 gallons in the Bennington 2250 GBR 2012. 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 2250 GBR 2012 is rated for 25 passengers, while the Bennington 25 SL I/O 2012 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 2250 GBR 2012 could be the deciding factor.
Bottom line: Choose the Bennington 2250 GBR 2012 if your priority is putting more people on the water — it handles 25 passengers and at 24,1 ft it has the deck room to back that rating up comfortably. The Bennington 25 SL I/O 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.
