Both the Sundance B22CC 2011 and the Sundance NX21 2010 are modified-V designs, both built in fibreglass, 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 B22CC 2011 at 21,8 ft versus Sundance NX21 2010 at 21,1 ft. Weight tells a clearer story for trailering families: the Sundance NX21 2010 tips the scales at 1 850 lbs - 260 lbs less than the Sundance B22CC 2011 at 1 590 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 B22CC 2011 has a 35-hp advantage over the Sundance NX21 2010's 115-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 2010 carries 45 gallons versus 33 gallons in the Sundance B22CC 2011. 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: Performance buyers should lean toward the Sundance B22CC 2011 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sundance NX21 2010 with its 115-hp rating is the more economical daily driver.
