INTERNATIONAL ONLY Vessel "A" is overtaking vessel "B" on open waters and will pass without changing course. Which action should vessel "A" take?

A Sound one long blast
B Sound two short blasts
C Sound the danger signal
D Not sound any whistle signals
AI Explanation

The correct answer is D) Not sound any whistle signals. According to the International Regulations for Preventing Collisions at Sea (COLREGS), when a vessel is overtaking another vessel, the overtaking vessel (Vessel A) shall keep out of the way of the vessel being overtaken (Vessel B) and shall not sound any whistle signals. The overtaking vessel is required to take early and substantial action to keep well clear of the vessel being overtaken. Sounding a whistle signal is not necessary in this situation, as the COLREGS dictate that the overtaking vessel must maneuver to safely pass the other vessel.
