When two boats share the same hull type — in this case both the Bennington 18 SLX 2013 and the Bennington 1850GL-Family Cruise & Combos Series 2009 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 18 SLX 2013 at 18,4 ft versus Bennington 1850GL-Family Cruise & Combos Series 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Bennington 1850GL-Family Cruise & Combos Series 2009 tips the scales at 1 909 lbs — 246 lbs less than the Bennington 18 SLX 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 SLX 2013 and 60 hp for the Bennington 1850GL-Family Cruise & Combos Series 2009. 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.

For family outings this is probably the sharpest distinction between the two. The Bennington 1850GL-Family Cruise & Combos Series 2009 is rated for 23 passengers, while the Bennington 18 SLX 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 1850GL-Family Cruise & Combos Series 2009 could be the deciding factor.

One place where both boats are genuinely identical is tube construction: both run 2 aluminum tubes at 23" diameter. That shared spec means stability and buoyancy characteristics are closely matched — the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
