The Storm Trysail Club is a private club dedicated to blue water sailing. Membership of about 1000 individuals is by invitation only to expert offshore sailors who have experienced storm conditions and are capable of commanding a sailing vessel in such conditions. Established in 1938, the club has a long history of sponsoring inshore, distance and offshore sailboat races, and supporting the interests and needs of sailors.

The purpose of the Club is to promote good fellowship among blue water sailors and ocean racing yachtsmen, and to encourage the sport of ocean racing and offshore cruising.  The Club is organized into 10 geographic stations giving it representation in the major sailing centers in America and a base for carrying out its purpose.
