When two boats share the same hull type — in this case both the Sundance B20CC 2011 and the Sundance NX23 2012 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?

Size is the most obvious dividing line here. The Sundance NX23 2012 measures 23,1 feet overall (2012), giving it roughly 3,3 additional feet of deck space compared to the Sundance B20CC 2011 at 19,8 feet (2011). Weight tells a clearer story for trailering families: the Sundance NX23 2012 tips the scales at 2 475 lbs — 2 328 lbs less than the Sundance B20CC 2011 at 147 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 250 hp, the Sundance NX23 2012 has a 120-hp advantage over the Sundance B20CC 2011's 130-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 NX23 2012 carries 72 gallons versus 33 gallons in the Sundance B20CC 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.
