When two boats share the same hull type — in this case both the Sundance B18CCR 2013 and the Sundance B20CCR 2008 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 B18CCR 2013 at 17,8 ft versus Sundance B20CCR 2008 at 19,0 ft. Weight tells a clearer story for trailering families: the Sundance B18CCR 2013 tips the scales at 1 355 lbs — 1 166 lbs more than the Sundance B20CCR 2008 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.

The power gap is worth calling out. Rated to 130 hp, the Sundance B20CCR 2008 has a 40-hp advantage over the Sundance B18CCR 2013's 90-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 B20CCR 2008 carries 33 gallons versus 24 gallons in the Sundance B18CCR 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.
