When two boats share the same hull type — in this case both the Sundance F17CCR 2009 and the Sundance SV171 2011 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 F17CCR 2009 at 16,8 ft versus Sundance SV171 2011 at 17,1 ft. At 141 lbs and 125 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 115 hp, the Sundance SV171 2011 has a 65-hp advantage over the Sundance F17CCR 2009's 50-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 SV171 2011 carries 34 gallons versus 24 gallons in the Sundance F17CCR 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Sundance SV171 2011 comes in at 1 lbs per hp versus 3 lbs per hp for the Sundance F17CCR 2009. 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.
