Definition
In or near an area of restricted visibility a power-driven vessel making way sounds one prolonged blast at intervals of not more than two minutes; under way but stopped and making no way, two prolonged blasts about two seconds apart. Sailing, fishing, towing, not under command, restricted and constrained vessels sound one prolonged followed by two short. A vessel at anchor rings the bell rapidly for about five seconds every minute. Vessels under 12 metres may use any other efficient signal.
