The Sundance B20CC 2009 vs Sundance F17 CC 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.
Size is the most obvious dividing line here. The Sundance B20CC 2009 measures 19,8 feet overall (2009), giving it roughly 3,8 additional feet of deck space compared to the Sundance F17 CC 2006 at 16,0 feet (2006). At 181 lbs and 101 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 — 90 hp for the Sundance B20CC 2009 and 70 hp for the Sundance F17 CC 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. Fuel capacity breaks the other way: the Sundance B20CC 2009 carries 33 gallons versus 24 gallons in the Sundance F17 CC 2006. 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 CC 2006 is rated for 7 passengers, while the Sundance B20CC 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance F17 CC 2006 could be the deciding factor.
Bottom line: Choose the Sundance F17 CC 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 B20CC 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
