When two boats share the same hull type — in this case both the Key West 177 SK 2013 and the Key West 186 DC 2010 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 — Key West 177 SK 2013 at 17,3 ft versus Key West 186 DC 2010 at 18,8 ft. At 11 lbs and 17 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 150 hp, the Key West 186 DC 2010 has a 60-hp advantage over the Key West 177 SK 2013's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Key West 177 SK 2013 carries 19 gallons versus 4 gallons in the Key West 186 DC 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
