The Sundance B22 CX 2006 vs Sundance NX21 2010 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Sundance B22 CX 2006 at 21,0 ft versus Sundance NX21 2010 at 21,1 ft. Weight tells a clearer story for trailering families: the Sundance B22 CX 2006 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 B22 CX 2006 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 B22 CX 2006. 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 B22 CX 2006 is rated for 14 passengers, while the Sundance NX21 2010 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance B22 CX 2006 could be the deciding factor.
Bottom line: Choose the Sundance B22 CX 2006 if your priority is putting more people on the water — it handles 14 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Sundance NX21 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
