What sound signal is used to indicate a vessel is altering its course to port?

The sound signal indicating that a vessel is altering its course to port is two short blasts. This communication is crucial for ensuring safe navigation and preventing collisions, particularly in situations where visibility is limited. The international maritime signaling conventions designate two short blasts as the clear and universally understood signal for making a turn to port, thereby alerting other vessels in the vicinity of the maneuvers being undertaken. This standardization is essential for maintaining safety on the water, allowing mariners to interpret signals accurately and respond accordingly.

Understanding the specific sound signals and their meanings is vital for both operational efficiency and safety in maritime environments.
