The Sundance F19FLX 2007 vs Sundance NX19 2013 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 F19FLX 2007 at 18,0 ft versus Sundance NX19 2013 at 18,8 ft. Weight tells a clearer story for trailering families: the Sundance NX19 2013 tips the scales at 1 475 lbs — 370 lbs less than the Sundance F19FLX 2007 at 1 105 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 115 hp, the Sundance NX19 2013 has a 25-hp advantage over the Sundance F19FLX 2007's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sundance NX19 2013 carries 29 gallons versus 24 gallons in the Sundance F19FLX 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 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 NX19 2013 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sundance F19FLX 2007 with its 90-hp rating is the more economical daily driver.
