When two boats share the same hull type — in this case both the Crest 18 2009 and the Crest 250SL - Stern Lounge Seating 2011 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 Crest 250SL - Stern Lounge Seating 2011 measures 21,8 feet overall (2011), giving it roughly 3,8 additional feet of deck space compared to the Crest 18 2009 at 18,0 feet (2009). Weight tells a clearer story for trailering families: the Crest 250SL - Stern Lounge Seating 2011 tips the scales at 2 315 lbs — 303 lbs less than the Crest 18 2009 at 2 012 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 115 hp, the Crest 250SL - Stern Lounge Seating 2011 has a 40-hp advantage over the Crest 18 2009's 75-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 Crest 250SL - Stern Lounge Seating 2011 is rated for 13 passengers, while the Crest 18 2009 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crest 250SL - Stern Lounge Seating 2011 could be the deciding factor.
Bottom line: Choose the Crest 250SL - Stern Lounge Seating 2011 if your priority is putting more people on the water — it handles 13 passengers and at 21,8 ft it has the deck room to back that rating up comfortably. The Crest 18 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
