Where the authorized officer so directs, or where the master is required to make a report under Regulation 13 (see Preparations for health clearance in Section H), no person other than the pilot, a customs officer, or an immigration officer, may, without the permission of the authorized officer, board or leave a ship until free pratique has been granted, and the master must take all reasonable steps to secure compliance with this requirement.
A Draught of Water and Freeboard Notice (MCA form MSF 2004, formerly FRE 13). The master must enter on it the ship's assigned freeboards and the particulars of loading, including: date and place of loading; actual draughts (forward, aft and mean); mean freeboards (actual and corrected); signatures of the master and an officer.
“+”(properly called a Pattee cross but often called a Maltese cross) means the ship was constructed under survey by Lloyd's Register surveyors; "100" means the ship is suitable for seagoing service. "A" means the ship was constructed or accepted into LR class and is maintained in good and efficient condition. "1"means she has good and efficient anchoring and mooring equipment.
Whereas a possessory lien depends on possession of property, a maritime lien does not depend on possession and is not extinguished by transfer of title in the property to a bona fide purchaser who is not notified of the lien's existence. A maritime lien can therefore "travel with the ship" to which it attaches, and is not lost through a change of ownership.
