Used Allied Seawind Sailboats for Sale

The Allied Seawind, often referred to as the Seawind 30 to distinguish it from its larger successor, occupies a hallowed position in the annals of American yachting. Designed by the esteemed naval architect Thomas Gillmer, the Seawind was the first fiberglass sailboat to successfully circumnavigate the globe—a feat accomplished by Alan Eddy aboard Apogee between 1964 and 1967. This voyage effectively silenced early critics of "glass" construction, proving that reinforced plastic could withstand the rigors of the open ocean. Built in Catskill, New York, the Seawind was characterized by its rugged, overbuilt hull and a traditional aesthetic that appealed to conservative offshore sailors. While it was available as a sloop, the vast majority were delivered as ketches, a rarity for a boat of only 30 feet, providing a versatile sail plan that defined the model’s identity as a miniature blue-water voyager.
