When two boats share the same hull type — in this case both the Sundance F17T 2013 and the Sundance NX19 2010 are modified vee designs with fiberglass 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 — Sundance F17T 2013 at 16,8 ft versus Sundance NX19 2010 at 18,8 ft. Weight tells a clearer story for trailering families: the Sundance NX19 2010 tips the scales at 1 475 lbs — 630 lbs less than the Sundance F17T 2013 at 845 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 — 70 hp for the Sundance F17T 2013 and 70 hp for the Sundance NX19 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.
For family outings this is probably the sharpest distinction between the two. The Sundance NX19 2010 is rated for 6 passengers, while the Sundance F17T 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance NX19 2010 could be the deciding factor.
Bottom line: Choose the Sundance NX19 2010 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 F17T 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
