Both the Sundance B20CC 2010 and the Sundance DX22 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 2010 at 19,8 ft versus Sundance DX22 2012 at 21,8 ft. Weight tells a clearer story for trailering families: the Sundance DX22 2012 tips the scales at 1 685 lbs - 215 lbs less than the Sundance B20CC 2010 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.
The power gap is worth calling out. Rated to 150 hp, the Sundance DX22 2012 has a 60-hp advantage over the Sundance B20CC 2010's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 33 gal and 33 gal - so range won't be a tiebreaker here.
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: Performance buyers should lean toward the Sundance DX22 2012 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sundance B20CC 2010 with its 90-hp rating is the more economical daily driver.
