The Sundance F17 FLX 2006 vs Sundance F19 FLX 2006 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 F19 FLX 2006 at 18,0 ft. At 1 045 lbs and 1 105 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 70 hp for the Sundance F17 FLX 2006 and 90 hp for the Sundance F19 FLX 2006. 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. Both carry nearly identical fuel loads — 24 gal and 24 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sundance F19 FLX 2006 is rated for 9 passengers, while the Sundance F17 FLX 2006 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance F19 FLX 2006 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Sundance F19 FLX 2006 comes in at 12 lbs per hp versus 15 lbs per hp for the Sundance F17 FLX 2006. 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 F19 FLX 2006 if your priority is putting more people on the water — it handles 9 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Sundance F17 FLX 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
