Able seamen—sail

For service on a sailing school vessel on any waters, an individual may be rated as able seaman—sail if the individual has at least 6 months’ service on deck on sailing school vessels, oceanographic research vessels powered primarily by sail, or equivalent sailing vessels operating on the oceans or navigable waters of the United States (including the Great Lakes).
