correction ... at least when I sat in "the chair" when a ship is in DRYDOCK the responsible party is the ship yard and transfers as soon as the ship crosses the line denoting the entrance .. for the common floating dock this was the 'sill' or edge of the dry dock. a ship in a "dockside" maintenance or repair period, responsibility remains the with the Master Had many experiences in both conditions . . . I'm always amazed how poorly cruise ships are set up for their mooring lines. A bundle fore and aft and nothing 'tween. If I'd tied up that way in ADAK or Dutch Harbor my ship would have been on the rocks the first night. Remember, a Disney ship blew away from the terminal in Canaveral not long ago and dropped the gangways .... tugs fortunately were close and responded to push the ship back against the pier.
