Question 20D1

Upon receiving a Distress alert, the most immediate and critical action for a ship station is to inform the Master or person in charge of the vessel. This allows for proper assessment of the situation, determination of the ship's ability to render assistance, and appropriate decision-making in accordance with maritime law and safety procedures. **A) Incorrect.** Ship stations should *not* immediately acknowledge a Distress alert via DSC. This responsibility primarily rests with coast stations. Immediate acknowledgment by multiple ships would cause congestion and confusion on distress frequencies. Ships only acknowledge if a coast station does not respond within a specific timeframe, or if they are in a position to assist. **C) Incorrect.** While relaying a Distress alert is a crucial procedure under certain circumstances (e.g., if the original alert is not acknowledged or if the distressed vessel is out of range of a coast station), it is not the *immediate* default action for every ship receiving an alert. Proper assessment is required first. **D) Incorrect.** Distress traffic holds the absolute highest priority in maritime communications, followed by Urgency traffic, then Safety traffic. Alerts concerning navigational hazards fall under Safety traffic, which is a lower priority than Distress or Urgency traffic.
