What does the term "target angle" refer to?

The term "target angle" specifically pertains to the vessel's relative bearing from another vessel, making this interpretation the most accurate. Understanding relative bearing is crucial for navigation and positioning in relation to other vessels, as it helps determine how to adjust course or speed to ensure safe and effective maneuvering.

When navigating, knowing the relative bearing allows an officer to assess how another vessel’s position might affect their vessel’s own trajectory and safety. This is especially important for collision avoidance and effective communication between vessels regarding their movements.

While the other options touch on relevant maritime concepts, they do not accurately define "target angle." For instance, the angle of approach to the port is more about the maneuvering dynamics of docking rather than the relationship between vessels. The ideal angle for docking is context-specific and does not apply universally to all navigational scenarios. Measuring the angle of waves hitting the vessel is a different concept related to weather and sea conditions rather than navigational bearing.
