When two boats share the same hull type — in this case both the Bennington 18 SLX 2013 and the Bennington 2874 QCW Sport Tower 2013 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 2874 QCW Sport Tower 2013 measures 30,1 feet overall (2013), giving it roughly 11,7 additional feet of deck space compared to the Bennington 18 SLX 2013 at 18,4 feet (2013). Weight tells a clearer story for trailering families: the Bennington 2874 QCW Sport Tower 2013 tips the scales at 3 881 lbs — 2 218 lbs less than the Bennington 18 SLX 2013 at 1 663 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 150 hp, the Bennington 2874 QCW Sport Tower 2013 has a 100-hp advantage over the Bennington 18 SLX 2013's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 26 gal and 23 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Bennington 2874 QCW Sport Tower 2013 is rated for 25 passengers, while the Bennington 18 SLX 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 2874 QCW Sport Tower 2013 could be the deciding factor.
Bottom line: Choose the Bennington 2874 QCW Sport Tower 2013 if your priority is putting more people on the water — it handles 25 passengers and at 30,1 ft it has the deck room to back that rating up comfortably. The Bennington 18 SLX 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
