Matching a pontoon Sweetwater SW 220-4 2013 against a trimaran Sweetwater SW 2586 2010 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Sweetwater SW 220-4 2013 at 23,7 ft versus Sweetwater SW 2586 2010 at 25,2 ft. Weight tells a clearer story for trailering families: the Sweetwater SW 220-4 2013 tips the scales at 2 801 lbs — 930 lbs more than the Sweetwater SW 2586 2010 at 1 871 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 220-4 2013 and 150 hp for the Sweetwater SW 2586 2010. 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 — 21 gal and 24 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sweetwater SW 2586 2010 is rated for 15 passengers, while the Sweetwater SW 220-4 2013 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sweetwater SW 2586 2010 could be the deciding factor.
Bottom line: Choose the Sweetwater SW 2586 2010 if your priority is putting more people on the water — it handles 15 passengers and at 25,2 ft it has the deck room to back that rating up comfortably. The Sweetwater SW 220-4 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.
