When two boats share the same hull type — in this case both the Bennington 1850FS 2008 and the Bennington 1875 GL 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 1850FS 2008 at 18,0 ft versus Bennington 1875 GL 2012 at 20,1 ft. At 1 909 lbs and 1 868 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 60 hp, the Bennington 1850FS 2008 has a 37-hp advantage over the Bennington 1875 GL 2012's 23-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
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.
Bottom line: The Bennington 1875 GL 2012 at 20,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Bennington 1850FS 2008 at 18,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
