When two boats share the same hull type — in this case both the Bennington 17 SLi 2011 and the Bennington 22SLi 2010 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?

Size is the most obvious dividing line here. The Bennington 22SLi 2010 measures 21,7 feet overall (2010), giving it roughly 4,3 additional feet of deck space compared to the Bennington 17 SLi 2011 at 17,4 feet (2011). Weight tells a clearer story for trailering families: the Bennington 22SLi 2010 tips the scales at 1 745 lbs — 254 lbs less than the Bennington 17 SLi 2011 at 1 491 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 Bennington 22SLi 2010 tops out at 23 hp. Engine specs for the Bennington 17 SLi 2011 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Bennington 22SLi 2010 carries 24 gallons versus 15 gallons in the Bennington 17 SLi 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Bennington 22SLi 2010 is rated for 23 passengers, while the Bennington 17 SLi 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 22SLi 2010 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.
