The Sundance F19FLX 2007 vs Sundance K16FLX 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 K16FLX 2013 at 15,8 ft. Weight tells a clearer story for trailering families: the Sundance F19FLX 2007 tips the scales at 1 105 lbs — 1 037 lbs more than the Sundance K16FLX 2013 at 68 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 90 hp, the Sundance F19FLX 2007 has a 40-hp advantage over the Sundance K16FLX 2013's 50-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 F19FLX 2007 carries 24 gallons versus 1 gallons in the Sundance K16FLX 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Sundance F19FLX 2007 is rated for 6 passengers, while the Sundance K16FLX 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance F19FLX 2007 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Sundance K16FLX 2013 comes in at 1 lbs per hp versus 12 lbs per hp for the Sundance F19FLX 2007. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Sundance F19FLX 2007 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Sundance K16FLX 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
