Welcome Aboard The Sag Harbor Yacht Club has been a colorful fixture on the waterfront of the historic village of Sag Harbor since 1899. The Clubs' mission is "To serve our members, the yachting community and the Community at Large." With its beautifully maintained docks accommodating large and small vessels of both sail and power, its spectacular Fourth of July fireworks display, the annual Maycroft Cup Regatta and its many contributions to our local organizations, the Sag Harbor Yacht Club more than fulfills its mission's mandate.
