What is required of a give-way vessel according to the regulations?

The correct response emphasizes that a give-way vessel must take early and substantial action to keep clear of the stand-on vessel. This requirement is critical to ensuring the safety of navigation and to prevent collisions at sea. The give-way vessel is defined as the one that must yield or give way to another vessel, which is typically determined by the relative positions and movements of the vessels involved.

By taking early and substantial action, the give-way vessel can effectively navigate away from the path of the stand-on vessel. This timely response reduces the risk of collision and allows the stand-on vessel to maintain its course and speed, contributing to the overall safety and efficiency of maritime traffic.

The other choices imply inadequate or inappropriate actions that could lead to unsafe conditions. Minimal action might not be enough to avoid a collision, while waiting for a signal could create unnecessary delays and increase risks. Maintaining a course until the last moment could result in a lack of necessary maneuvering space, making it difficult to avoid a collision if the stand-on vessel does not alter its path. Thus, the requirement for the give-way vessel is to be proactive and assertive in ensuring a clear passage.
