What is the minimum range of the masthead light on vessels that are 50 meters or more in length?

For vessels that are 50 meters or more in length, the minimum range of the masthead light is indeed six miles. This requirement is specified in the International Regulations for Preventing Collisions at Sea (COLREGs). The masthead light is an important navigational light, typically placed at the highest point of the vessel, which serves to indicate the presence of the vessel to others navigating in the area. The six-mile range ensures that the vessel is visible to other mariners at a distance, providing ample warning and aiding in safe navigation.

In the context of this regulation, the other ranges provided do not meet the criteria established for the category of vessels over 50 meters. For example, smaller vessels or those of different lengths have different minimum visibility requirements for their masthead lights, but for vessels of this size, a range of six miles is necessary to enhance maritime safety and prevent collisions at sea.
