When two boats share the same hull type — in this case both the Sundance FX25 2013 and the Sundance NX25 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 FX25 2013 at 24,9 ft versus Sundance NX25 2010 at 25,1 ft. Weight tells a clearer story for trailering families: the Sundance NX25 2010 tips the scales at 2 735 lbs — 2 709 lbs less than the Sundance FX25 2013 at 26 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 power gap is worth calling out. Rated to 300 hp, the Sundance FX25 2013 has a 50-hp advantage over the Sundance NX25 2010's 250-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 75 gal and 72 gal — so range won't be a tiebreaker here.
Both boats are rated for 10 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the Sundance FX25 2013 and its 300-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sundance NX25 2010 with its 250-hp rating is the more economical daily driver.
