The Sundance F17 FLX 2006 vs Sundance SV19 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 F17 FLX 2006 at 16,0 ft versus Sundance SV19 2013 at 18,5 ft. Weight tells a clearer story for trailering families: the Sundance F17 FLX 2006 tips the scales at 1 045 lbs — 900 lbs more than the Sundance SV19 2013 at 145 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 150 hp, the Sundance SV19 2013 has a 80-hp advantage over the Sundance F17 FLX 2006's 70-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 F17 FLX 2006 carries 24 gallons versus 4 gallons in the Sundance SV19 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 F17 FLX 2006 is rated for 7 passengers, while the Sundance SV19 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 F17 FLX 2006 could be the deciding factor.
Bottom line: Choose the Sundance F17 FLX 2006 if your priority is putting more people on the water — it handles 7 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Sundance SV19 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.
