When two boats share the same hull type — in this case both the Key West 177 SK 2010 and the Key West 2020 DC 2011 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 2010 at 17,3 ft versus Key West 2020 DC 2011 at 20,2 ft. Weight tells a clearer story for trailering families: the Key West 2020 DC 2011 tips the scales at 195 lbs — 184 lbs less than the Key West 177 SK 2010 at 11 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 2020 DC 2011 has a 110-hp advantage over the Key West 177 SK 2010'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 2010 carries 19 gallons versus 6 gallons in the Key West 2020 DC 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Bottom line: The Key West 2020 DC 2011 at 20,2 ft is the right call if deck space, comfort, and entertaining are top of your list. The Key West 177 SK 2010 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.
