The Sundance F19FLX 2007 vs Sundance NX19 2010 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 2010 at 18,8 ft. Weight tells a clearer story for trailering families: the Sundance NX19 2010 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.
Both boats share a closely matched power ceiling — 90 hp for the Sundance F19FLX 2007 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. Fuel capacity breaks the other way: the Sundance NX19 2010 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 F19FLX 2007 and its 90-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sundance NX19 2010 with its 70-hp rating is the more economical daily driver.
