Wally Ross purchased Hard Sails, Inc. in 1954 from a friend, William Hard. Ross had been an account executive at a local Long Island radio station and Hard Sails was one of his accounts. Hard Sails, Inc. was based in Islip, Long Island. Ross’s subsequent success at sailmaking came during the exploding yachting boom during the early 1960s when, coincidentally, synthetic materials were first available for the crafting of sails. Ross’s work in Dacron gave his staff a medium that held its shape, allowing for the application of aerodynamic theory to sailing. A material holding shape also allowed for relative mass production, especially when compared to the older, individual sailmaking techniques using Egyptian cotton. By the mid-1960s, Hard Sails was using a new device – the computer – to accelerate the design process, laying the foundations for Gentry’s work between 1969 and 1971. Ross’s seminal work, Sail Power, was the intellectual capstone of the previous decade’s intellectualization of sail.
