When two boats share the same hull type — in this case both the Sundance B18CCR 2010 and the Sundance F17CC 2009 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 2010 at 17,8 ft versus Sundance F17CC 2009 at 16,8 ft. Weight tells a clearer story for trailering families: the Sundance B18CCR 2010 tips the scales at 1 355 lbs — 1 220 lbs more than the Sundance F17CC 2009 at 135 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 — 75 hp for the Sundance B18CCR 2010 and 60 hp for the Sundance F17CC 2009. 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 B18CCR 2010 carries 33 gallons versus 24 gallons in the Sundance F17CC 2009. 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 B18CCR 2010 is rated for 6 passengers, while the Sundance F17CC 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance B18CCR 2010 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Sundance F17CC 2009 comes in at 2 lbs per hp versus 18 lbs per hp for the Sundance B18CCR 2010. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
