When two boats share the same hull type — in this case both the Sweetwater SW 240 2012 and the Sweetwater SW 2586 DF 2009 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?
On paper these two are close siblings in the size department — Sweetwater SW 240 2012 at 26,0 ft versus Sweetwater SW 2586 DF 2009 at 25,0 ft. Weight tells a clearer story for trailering families: the Sweetwater SW 240 2012 tips the scales at 3 058 lbs — 2 792 lbs more than the Sweetwater SW 2586 DF 2009 at 266 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 — 150 hp for the Sweetwater SW 240 2012 and 150 hp for the Sweetwater SW 2586 DF 2009. 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 24 gal — so range won't be a tiebreaker here.
Both boats are rated for 15 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Sweetwater SW 240 2012 and Sweetwater SW 2586 DF 2009 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
