When two boats share the same hull type — in this case both the Key West 176 DC 2009 and the Key West 1900 CC 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 176 DC 2009 at 17,0 ft versus Key West 1900 CC 2011 at 19,2 ft. Weight tells a clearer story for trailering families: the Key West 176 DC 2009 tips the scales at 135 lbs — 119 lbs more than the Key West 1900 CC 2011 at 16 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.
Both boats share a closely matched power ceiling — 140 hp for the Key West 176 DC 2009 and 150 hp for the Key West 1900 CC 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 4 gal and 6 gal — so range won't be a tiebreaker here.
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: The Key West 1900 CC 2011 at 19,2 ft is the right call if deck space, comfort, and entertaining are top of your list. The Key West 176 DC 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.
