When two boats share the same hull type — in this case both the Sundance B20CC 2009 and the Sundance F17CC 2012 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Sundance B20CC 2009 measures 19,8 feet overall (2009), giving it roughly 3,1 additional feet of deck space compared to the Sundance F17CC 2012 at 16,8 feet (2012). Weight tells a clearer story for trailering families: the Sundance F17CC 2012 tips the scales at 975 lbs — 794 lbs less than the Sundance B20CC 2009 at 181 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.

Both boats share a closely matched power ceiling — 90 hp for the Sundance B20CC 2009 and 70 hp for the Sundance F17CC 2012. 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 F17CC 2012. 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 B20CC 2009 is rated for 6 passengers, while the Sundance F17CC 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance B20CC 2009 could be the deciding factor.
