The Sundance F19T 2013 vs Sundance SV171Bay 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department - Sundance F19T 2013 at 18,8 ft versus Sundance SV171Bay 2007 at 17,0 ft. Weight tells a clearer story for trailering families: the Sundance SV171Bay 2007 tips the scales at 1 550 lbs - 555 lbs less than the Sundance F19T 2013 at 995 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 - 90 hp for the Sundance F19T 2013 and 90 hp for the Sundance SV171Bay 2007. 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.
For family outings this is probably the sharpest distinction between the two. The Sundance F19T 2013 is rated for 6 passengers, while the Sundance SV171Bay 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance F19T 2013 could be the deciding factor.
Bottom line: Choose the Sundance F19T 2013 if your priority is putting more people on the water - it handles 6 passengers and at 18,8 ft it has the deck room to back that rating up comfortably. The Sundance SV171Bay 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
