The Bennington 18 SL 2013 vs Bennington 1850 GL 2007 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.
On paper these two are close siblings in the size department - Bennington 18 SL 2013 at 18,4 ft versus Bennington 1850 GL 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Bennington 1850 GL 2007 tips the scales at 1 909 lbs - 246 lbs less than the Bennington 18 SL 2013 at 1 663 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.
Both boats share a closely matched power ceiling - 50 hp for the Bennington 18 SL 2013 and 60 hp for the Bennington 1850 GL 2007. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 26 gal and 26 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Bennington 1850 GL 2007 is rated for 23 passengers, while the Bennington 18 SL 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 1850 GL 2007 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Bennington 1850 GL 2007 comes in at 32 lbs per hp versus 33 lbs per hp for the Bennington 18 SL 2013. 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 1850 GL 2007 is an inflatable design - lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Bennington 18 SL 2013 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 1850 GL 2007 if your priority is putting more people on the water - it handles 23 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Bennington 18 SL 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
