COLREGs · Rule 36
Signals to Attract Attention
TL;DR
Any vessel may, if necessary to attract another's attention, make light or sound signals that cannot be mistaken for a signal authorised elsewhere in the rules, or direct the beam of her searchlight in danger's direction (without embarrassing other vessels).
