When two boats share the same hull type — in this case both the Sundance B20CCR 2009 and the Sundance DX18 2013 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 B20CCR 2009 at 19,8 ft versus Sundance DX18 2013 at 17,8 ft. Weight tells a clearer story for trailering families: the Sundance DX18 2013 tips the scales at 1 395 lbs — 1 206 lbs less than the Sundance B20CCR 2009 at 189 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.

Both boats share a closely matched power ceiling — 90 hp for the Sundance B20CCR 2009 and 90 hp for the Sundance DX18 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Sundance B20CCR 2009 carries 33 gallons versus 24 gallons in the Sundance DX18 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 6 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.
