When two boats share the same hull type — in this case both the Sundance DX22 2013 and the Sundance NX21 2010 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?

On paper these two are close siblings in the size department — Sundance DX22 2013 at 21,8 ft versus Sundance NX21 2010 at 21,1 ft. Weight tells a clearer story for trailering families: the Sundance DX22 2013 tips the scales at 1 745 lbs — 1 560 lbs more than the Sundance NX21 2010 at 185 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 2013 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 24 gallons in the Sundance DX22 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.
