The Sundance F19CCR 2007 vs Sundance NX21 2009 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.
Size is the most obvious dividing line here. The Sundance NX21 2009 measures 21,1 feet overall (2009), giving it roughly 3,1 additional feet of deck space compared to the Sundance F19CCR 2007 at 18,0 feet (2007). At 107 lbs and 185 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.
The power gap is worth calling out. Rated to 115 hp, the Sundance NX21 2009 has a 25-hp advantage over the Sundance F19CCR 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 NX21 2009 carries 45 gallons versus 24 gallons in the Sundance F19CCR 2007. 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 NX21 2009 is rated for 8 passengers, while the Sundance F19CCR 2007 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance NX21 2009 could be the deciding factor.
Bottom line: Choose the Sundance NX21 2009 if your priority is putting more people on the water — it handles 8 passengers and at 21,1 ft it has the deck room to back that rating up comfortably. The Sundance F19CCR 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
