Why should a navigator be aware of this?

A navigator needs to have a good understanding of ship interaction because it can have a significant impact on the vessel’s course, speed, and stability.

A navigator needs to be able to anticipate the movements of other ships in the vicinity, as well as the potential effects of external factors such as wind and currents. By understanding ship interaction, a navigator can make informed decisions about the vessel’s course and speed to ensure the safety of the crew and cargo on board.

Additionally, a good understanding of ship interaction can help a navigator to avoid collisions and other potentially dangerous situations that may arise when multiple vessels are operating near each other.
