This text has been developed to provide a firm foundation for men and women working toward earning US Coast Guard licenses to operate auxiliary-powered sailing yachts and vessels. Initially created as a course curriculum for classes in sail vessel operations at the Maine Maritime Academy, this revised and updated second edition contains new material on bridge resource management, risk assessment, safety aloft, and more. Designed to accompany the sailor as a study guide and point of reference, it calls attention to the myriad constant and critical elements of professional yacht and vessel management in both theory and practice. Subjects covered include seamanship aboard sailing vessels, relevant hydrodynamic and aerodynamic theory, basic and advanced sailing maneuvers, planning and managing for crew and vessel safety, meteorology for sailors, heavy-weather sailing, emergencies at sea, and vessel administration as related to Coast Guard rules and regulations.
