Applying the Rule(s) and comments:
In accordance with Rule 36
(Signals to attract attention), if necessary to attract the attention of another vessel any vessel may make light or sound signals that cannot be mistaken for any signal authorised elsewhere in these Rules, or may direct the beam of her searchlight in the direction of the danger, in such a way as not to embarrass any vessel. Any light to attract the attention of another vessel shall be such that it cannot be mistaken for any aid to navigation. For the purpose of this Rule the use of high-intensity intermittent or revolving lights, such as strobe lights, shall be avoided. Comments: The following signals are commonly used to attract attention: - the beam of a searchlight directed toward the dangerous area, - two short blasts followed by one prolonged blast (Morse Code U), - two short flashes followed by one prolonged flash (Morse Code U), - hand flare showing a white light.
