Book excerpt: The fascinating story of fiberglass boats and the mavericks who dreamed them. Nine out of ten sailors today own sturdy, often beautiful fiberglass craft. Fiberglass brought boating to the non-rich, but the history of that revolution has never been told. Daniel Spurr rectifies this omission with his highly readable and affectionate account of the fiberglass boat, from its earliest incarnation in World War II to the present day. In the early days, when shoestring genius was unfettered by industrial efficiency, therewere boats with tailfins, boats baked in ovens, and boats designed to be dropped from planes. The voyage from those first ugly ducklings to the graceful boats of the 1990s makes a riveting adventure of triumph and ruin. Along the way, Spurr profiles landmark designs that now set the standards in the used-boat market, and he portrays the revolution in human terms, introducing us to the vivid personalities who invented--often in their garages and rarely at a profit--the world of boating we know today.
