When two boats share the same hull type — in this case both the Sweetwater SW 2386 2010 and the Sweetwater SWT 1770 F 2010 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 2386 2010 measures 23,2 feet overall (2010), giving it roughly 6,2 additional feet of deck space compared to the Sweetwater SWT 1770 F 2010 at 17,0 feet (2010). At 174 lbs and 126 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 135 hp, the Sweetwater SW 2386 2010 has a 75-hp advantage over the Sweetwater SWT 1770 F 2010's 60-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 Sweetwater SW 2386 2010 is rated for 13 passengers, while the Sweetwater SWT 1770 F 2010 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sweetwater SW 2386 2010 could be the deciding factor.
Bottom line: Choose the Sweetwater SW 2386 2010 if your priority is putting more people on the water — it handles 13 passengers and at 23,2 ft it has the deck room to back that rating up comfortably. The Sweetwater SWT 1770 F 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
