Both the Sundance B20CC 2013 and the Sundance DX20 2012 are modified-V designs, the first built in fibreglass and the second in composite, so 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?
On paper these two are close siblings in the size department - Sundance B20CC 2013 at 19,8 ft versus Sundance DX20 2012 at 19,8 ft. Weight tells a clearer story for trailering families: the Sundance DX20 2012 tips the scales at 1 575 lbs - 105 lbs less than the Sundance B20CC 2013 at 1 470 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 - 130 hp for the Sundance B20CC 2013 and 130 hp for the Sundance DX20 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 DX20 2012 carries 33 gallons versus 24 gallons in the Sundance B20CC 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 8 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Sundance B20CC 2013 and Sundance DX20 2012 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
