When two boats share the same hull type — in this case both the Bennington 20SLi 2010 and the Bennington 2574 GCW 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?

Size is the most obvious dividing line here. The Bennington 2574 GCW 2012 measures 27,1 feet overall (2012), giving it roughly 7,4 additional feet of deck space compared to the Bennington 20SLi 2010 at 19,7 feet (2010). Weight tells a clearer story for trailering families: the Bennington 20SLi 2010 tips the scales at 1 611 lbs — 1 309 lbs more than the Bennington 2574 GCW 2012 at 302 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 — 23 hp for the Bennington 20SLi 2010 and 25 hp for the Bennington 2574 GCW 2012. 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. Both carry nearly identical fuel loads — 24 gal and 25 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Bennington 2574 GCW 2012 is rated for 25 passengers, while the Bennington 20SLi 2010 caps at 23. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 2574 GCW 2012 could be the deciding factor.
