When two boats share the same hull type — in this case both the Bennington 1850 GL 2011 and the Bennington 20 SF 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 1850 GL 2011 at 19,3 ft versus Bennington 20 SF 2013 at 20,4 ft. Weight tells a clearer story for trailering families: the Bennington 1850 GL 2011 tips the scales at 1 909 lbs — 148 lbs more than the Bennington 20 SF 2013 at 1 761 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 — 60 hp for the Bennington 1850 GL 2011 and 70 hp for the Bennington 20 SF 2013. 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. Fuel capacity breaks the other way: the Bennington 1850 GL 2011 carries 26 gallons versus 21 gallons in the Bennington 20 SF 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 23 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

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.
