Both the Bennington 20 SFi 2011 and the Bennington 2075RLi 2010 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 20 SFi 2011 at 20,4 ft versus Bennington 2075RLi 2010 at 22,2 ft. Weight tells a clearer story for trailering families: the Bennington 2075RLi 2010 tips the scales at 2 553 lbs - 942 lbs less than the Bennington 20 SFi 2011 at 1 611 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 SFi 2011 has a 45-hp advantage over the Bennington 2075RLi 2010's 25-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 24 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 2075RLi 2010 is rated for 25 passengers, while the Bennington 20 SFi 2011 caps at 23. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 2075RLi 2010 could be the deciding factor.
Both are 2-tube and 23-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity - more so than most buyers realize when comparing on paper.
Bottom line: Choose the Bennington 2075RLi 2010 if your priority is putting more people on the water - it handles 25 passengers and at 22,2 ft it has the deck room to back that rating up comfortably. The Bennington 20 SFi 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 23 that costs less to run day-to-day.
