What signal indicates a vessel's intention to alter course to port?

The signal that indicates a vessel's intention to alter course to port is represented by two short blasts. This signal is part of the standard communication between vessels regarding their maneuvers. When a vessel intends to change its course to port, it will sound two short blasts on its whistle. This action is essential for maintaining safety and preventing collisions at sea, as it clearly communicates the vessel's intentions to other nearby vessels. Understanding these signals is crucial for navigational safety and adherence to maritime rules and regulations.
