What action should a give-way vessel take when another vessel is on a collision course?

When a give-way vessel is on a collision course with another vessel, it is crucial that it alters its course to avoid a collision. The primary responsibility of the give-way vessel is to take action to ensure safety and prevent an accident. By changing course, the give-way vessel actively demonstrates its intention to avoid the other vessel, thereby mitigating the risk of a collision.

Maintaining course and speed would increase the likelihood of an accident. Signaling the other vessel might communicate awareness of the situation but does not directly address the need to take evasive action. Speeding up to pass quickly poses additional dangers, as it could complicate the situation and prevent the crew from effectively navigating away from potential danger. Therefore, altering course is the safest and most prudent action a give-way vessel can take to ensure the safety of both vessels involved.
