Which alarm is activated when there is a risk of a ship colliding with another object?

The activation of a collision alarm is specifically designed to alert the crew to the imminent risk of a ship colliding with another object, be it another vessel, an obstacle, or coastline. This safety mechanism serves to enhance situational awareness and prompt necessary actions to prevent accidents that could cause significant damage to the ship, its crew, and other vessels or infrastructure. The collision alarm typically integrates data from navigation systems and radar to detect potential hazards and coordinates, ensuring timely warnings when the distance to another object becomes critically close.

The fire alarm, emergency alarm, and anchor watch alarm serve other distinct purposes related to safety and operational alertness on a vessel. The fire alarm focuses on detecting smoke or heat indicating a fire, the emergency alarm signals various types of emergencies beyond collision risks, and the anchor watch alarm is meant to alert the crew about the boat's anchor integrity and monitor for any unwanted drifting. These alarms, while crucial in their respective contexts, do not directly address the specific scenario of potential collisions at sea.
