Both the Key West 186 DC 2013 and the Key West 196 BR 2010 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 - Key West 186 DC 2013 at 18,8 ft versus Key West 196 BR 2010 at 19,5 ft. At 1 700 lbs and 1 800 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 200 hp, the Key West 196 BR 2010 has a 50-hp advantage over the Key West 186 DC 2013's 150-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 196 BR 2010 carries 60 gallons versus 40 gallons in the Key West 186 DC 2013. 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 Key West 196 BR 2010 and its 200-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Key West 186 DC 2013 with its 150-hp rating is the more economical daily driver.
