High Quality Content by WIKIPEDIA articles! Caribbean Sailing Yachts, also known as CSY, are heavy-displacement recreational sailboats built during the 1970s and 1980s in Tampa, Florida. CSY went out of business in the early 1980s; however, the well-founded boats have continued to sail the world`s oceans for the past two decades. CSY had a rather unique script logo which was carried through on their brass companionway medallion, their sales literature, dishes, and perhaps was part of the trailerboard design or vice versa.
