What is the best course of action if two vessels are on a collision course?

When two vessels are on a collision course, the best course of action is for one vessel to take evasive maneuvers. This action is crucial in preventing a collision and is aligned with the general principles outlined in the COLREGs. According to the International Regulations for Preventing Collisions at Sea, vessels are required to take appropriate and timely action to avoid collisions when there is a risk.

Evasive maneuvers may include altering course and/or speed to ensure that the vessels can pass each other safely. It is important for one vessel to take the initiative, as attempting to maintain the current course and speed by both vessels could lead to a collision, especially if they are unable to communicate and coordinate their movements effectively.

Maintaining speed and course is typically advised when the other vessel has the obligation to give way or in certain scenarios where changing course or speed could increase the risk of an accident. However, in a direct collision course situation, taking proactive measures to avoid potential contact is essential.

Additionally, simply speeding up or sounding the whistle would not necessarily contribute to a safe resolution of the situation. Speeding up could exacerbate the risk of collision, and sounding the whistle is more of a communication measure rather than a corrective action to change the paths of
