Both the Sundance F17CCR 2009 and the Sundance SV171 2012 are modified-V designs, both built in fibreglass, so 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 2012 at 17,1 ft. Weight tells a clearer story for trailering families: the Sundance F17CCR 2009 tips the scales at 1 410 lbs - 160 lbs more than the Sundance SV171 2012 at 1 250 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 115 hp, the Sundance SV171 2012 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 2012 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 2012 comes in at 11 lbs per hp versus 28 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.
