    Examining Officer is responsible for informing Masters
    of incoming vessels what restrictions (if any) are in force.
36. When a merchant vessel is under way, merchant vessels
    at anchor or secured are to show anchor lights (see paragraph 42)

Captains, Masters, and others in charge of merchant vessels are
hereby warned to observe any orders given by the patrols. All
merchant vessels are subject to inspection and search by these
patrols. Disobedience of orders given by these patrols renders a
