Both the Key West 177 SK 2009 and the Key West 225 DC 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?
Size is the most obvious dividing line here. The Key West 225 DC 2009 measures 22,0 feet overall (2009), giving it roughly 5,0 additional feet of deck space compared to the Key West 177 SK 2009 at 17,0 feet (2009). Weight tells a clearer story for trailering families: the Key West 225 DC 2009 tips the scales at 2 700 lbs - 1 600 lbs less than the Key West 177 SK 2009 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 250 hp, the Key West 225 DC 2009 has a 160-hp advantage over the Key West 177 SK 2009'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 225 DC 2009 carries 100 gallons versus 19 gallons in the Key West 177 SK 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Bottom line: The Key West 225 DC 2009 at 22,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Key West 177 SK 2009 at 17,0 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.
