, which stands for Caribbean Sailing Yachts, are heavy-displacement recreational sailboats built in Tampa, Florida during the 1970s and 1980s. CSY closed their doors for good in the early 1980s, although the yachts have continued to sail the world's oceans since then. The CSY yachts were sold directly from the factory, without any dealerships or middle-men. Two books were published showing all stages of construction of these boats. One was entitled “CSY Guide to Buying a Yacht.” and was used as the primary means of promotion. CSY also used a film strip, plant tours, boat shows and trial sails as sales tools. Another book was published; a 38-page soft-cover “CSY Charter Manual” in 1979. CSY was the first company to come up with the concept of charter ownership, pioneered by CSY founder Dr. John Van Ost, a New Jersey dentist with a love of sailing. CSY developed and perfected the “charter lease back” program, in which, an individual purchased the yacht and subsequently placed it into the charter fleet to cover the cost of the initial payments.
