Both the Sundance K16CC 2010 and the Sundance SV171 2009 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 K16CC 2010 at 15,8 ft versus Sundance SV171 2009 at 17,1 ft. Weight tells a clearer story for trailering families: the Sundance SV171 2009 tips the scales at 1 430 lbs - 750 lbs less than the Sundance K16CC 2010 at 680 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 90 hp, the Sundance SV171 2009 has a 50-hp advantage over the Sundance K16CC 2010's 40-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 2009 carries 34 gallons versus 10 gallons in the Sundance K16CC 2010. 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 SV171 2009 is rated for 5 passengers, while the Sundance K16CC 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance SV171 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Sundance SV171 2009 comes in at 16 lbs per hp versus 17 lbs per hp for the Sundance K16CC 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.
