D) There is doubt that another vessel is taking sufficient action

Answer 1

Five or more short blasts of a ship's whistle signal uncertainty or doubt about another vessel's actions, indicating a potential risk of collision.

Step-by-step explanation:

When a vessel's whistle emits five or more short blasts, it is a signal indicating doubt or uncertainty in the intentions or actions of the other vessel.

This signal does not refer to altering course or maintaining course and speed, but rather communicates a concern that the other vessel's maneuvers may not be enough to avoid a collision or other dangerous situation. It serves as a warning that the vessel blasting the signal cannot predict the other vessel's movements with certainty, and therefore, there may be a risk of collision.

When a vessel's whistle emits five or more short blasts, it indicates that there is doubt that another vessel is taking sufficient action. This is a signal to convey concern about the actions being taken by another vessel in terms of maintaining proper course and speed. It serves as a warning to both vessels to be cautious and aware of each other.
