Both the Key West 177 SK 2013 and the Key West 210 BR 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?
Size is the most obvious dividing line here. The Key West 210 BR 2012 measures 21,1 feet overall (2012), giving it roughly 3,8 additional feet of deck space compared to the Key West 177 SK 2013 at 17,3 feet (2013). Weight tells a clearer story for trailering families: the Key West 210 BR 2012 tips the scales at 1 800 lbs - 700 lbs less than the Key West 177 SK 2013 at 1 100 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 200 hp, the Key West 210 BR 2012 has a 110-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 210 BR 2012 carries 60 gallons versus 19 gallons in the Key West 177 SK 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Bottom line: The Key West 210 BR 2012 at 21,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Key West 177 SK 2013 at 17,3 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
