When two boats share the same hull type — in this case both the Sundance F17CC 2011 and the Sundance SV186 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 F17CC 2011 at 16,8 ft versus Sundance SV186 2009 at 18,1 ft. Weight tells a clearer story for trailering families: the Sundance F17CC 2011 tips the scales at 975 lbs — 818 lbs more than the Sundance SV186 2009 at 157 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 — 70 hp for the Sundance F17CC 2011 and 90 hp for the Sundance SV186 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 F17CC 2011 carries 24 gallons versus 4 gallons in the Sundance SV186 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.
Bottom line: Performance buyers should lean toward the Sundance SV186 2009 and its 90-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sundance F17CC 2011 with its 70-hp rating is the more economical daily driver.
