When two boats share the same hull type — in this case both the Sweetwater SW 1570 2011 and the Sweetwater SW 200-4 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 Sweetwater SW 200-4 2011 measures 22,0 feet overall (2011), giving it roughly 7,0 additional feet of deck space compared to the Sweetwater SW 1570 2011 at 15,0 feet (2011). Weight tells a clearer story for trailering families: the Sweetwater SW 200-4 2011 tips the scales at 2 554 lbs — 719 lbs less than the Sweetwater SW 1570 2011 at 1 835 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 Sweetwater SW 200-4 2011 tops out at 115 hp. Engine specs for the Sweetwater SW 1570 2011 aren't listed — confirm with a dealer before selecting an outboard.
For family outings this is probably the sharpest distinction between the two. The Sweetwater SW 200-4 2011 is rated for 11 passengers, while the Sweetwater SW 1570 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sweetwater SW 200-4 2011 could be the deciding factor.
Bottom line: Choose the Sweetwater SW 200-4 2011 if your priority is putting more people on the water — it handles 11 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Sweetwater SW 1570 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
