The Bennington 1650 GLi 2006 vs Bennington 25 SL I/O 2012 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Bennington 25 SL I/O 2012 measures 24,3 feet overall (2012), giving it roughly 8,3 additional feet of deck space compared to the Bennington 1650 GLi 2006 at 16,0 feet (2006). Weight tells a clearer story for trailering families: the Bennington 25 SL I/O 2012 tips the scales at 3 099 lbs - 1 724 lbs less than the Bennington 1650 GLi 2006 at 1 375 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 270-hp advantage over the Bennington 1650 GLi 2006's 50-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 15 gallons in the Bennington 1650 GLi 2006. 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 25 SL I/O 2012 is rated for 14 passengers, while the Bennington 1650 GLi 2006 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 25 SL I/O 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Bennington 25 SL I/O 2012 comes in at 10 lbs per hp versus 28 lbs per hp for the Bennington 1650 GLi 2006. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
The Bennington 1650 GLi 2006 is an inflatable design - lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Bennington 25 SL I/O 2012 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: Choose the Bennington 25 SL I/O 2012 if your priority is putting more people on the water - it handles 14 passengers and at 24,3 ft it has the deck room to back that rating up comfortably. The Bennington 1650 GLi 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
