What is the minimum visibility of a masthead light on a vessel of 25m in length?

For a vessel of 25 meters in length, the regulations stipulate that the minimum visibility of the masthead light is established to be 4 nautical miles. The masthead light, which is located at the front of the vessel, plays a crucial role in ensuring that other vessels can see and identify the presence and heading of the vessel, especially during the night or in conditions of reduced visibility.

According to the International Regulations for Preventing Collisions at Sea (COLREGs), the visibility of the masthead light is directly related to the size and type of the vessel. For vessels that are 12 meters or more but less than 50 meters in length, which includes a 25-meter vessel, this requirement varies, with the specific distance of 4 nautical miles designated for masthead lights.

This regulation is important for maritime safety, as it helps prevent collisions by allowing vessels to detect each other from a sufficient distance, allowing for proper maneuvering and navigation.
