Navigation Rules: Crossing Paths

The next situation to cover is, what to do when two power-driven vessels cross paths. In this situation, the boater approaching on the port side is the give-way vessel and must yield.

Crossing Paths

In this diagram, Vessel A is the give-way vessel and must take action to avoid crossing the path of Vessel B.

So Vessel A must let Vessel B know their intentions. Signal with one short blast to indicate the intention to cross port-to-port and then turn starboard to avoid crossing or collision. Vessel B should return with one short burst, signaling they understand.
