Bennington 1850GL-S Series 2009 vs Bennington 20 SF 2012: A Close Look at Two Pontoon Boats

Both the Bennington 1850GL-S Series 2009 and the Bennington 20 SF 2012 are pontoon designs, both built in aluminium, so 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 1850GL-S Series 2009 at 18,6 ft versus Bennington 20 SF 2012 at 20,4 ft. Weight tells a clearer story for trailering families: the Bennington 1850GL-S Series 2009 tips the scales at 1 909 lbs - 198 lbs more than the Bennington 20 SF 2012 at 1 711 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 70 hp, the Bennington 20 SF 2012 has a 68-hp advantage over the Bennington 1850GL-S Series 2009's 2-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Bennington 20 SF 2012 is rated for 23 passengers, while the Bennington 1850GL-S Series 2009 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 20 SF 2012 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.

Bottom line: Choose the Bennington 20 SF 2012 if your priority is putting more people on the water - it handles 23 passengers and at 20,4 ft it has the deck room to back that rating up comfortably. The Bennington 1850GL-S Series 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.

Bennington 1850GL-S Series 2009 vs Bennington 20 SF 2012 - Common Questions

Which is the larger boat - the Bennington 1850GL-S Series 2009 or the Bennington 20 SF 2012?
The Bennington 20 SF 2012 is the longer of the two at 20,4 feet overall. The Bennington 1850GL-S Series 2009 comes in at 18,6 feet, making it roughly 1,8 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Bennington 1850GL-S Series 2009 or the Bennington 20 SF 2012?
For trailering, the Bennington 20 SF 2012 has the edge at 1 711 lbs dry weight versus 1 909 lbs for the Bennington 1850GL-S Series 2009. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Bennington 20 SF 2012 is rated to a maximum of 70 hp, giving it the larger power ceiling. The Bennington 1850GL-S Series 2009 tops out at 2 hp. Keep in mind that maximum ratings are just that - matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Bennington 1850GL-S Series 2009 is Coast Guard rated for 2 passengers, while the Bennington 20 SF 2012 is certified for 23. Note that legal capacity and comfortable capacity aren't always the same thing - on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Are the Bennington 1850GL-S Series 2009 and Bennington 20 SF 2012 from the same manufacturer?
Yes - both the Bennington 1850GL-S Series 2009 and the Bennington 20 SF 2012 are built by Bennington. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
