What is the protocol for vessels engaged in fishing at night under the Rules?

Vessels engaged in fishing at night are required to display the appropriate lights and shapes to indicate their activity and ensure safe navigation. According to the Rules of the Road, specifically Rule 25, fishing vessels must show specific head-on lights which consist of two all-around lights, one green and one white, as well as the fishing shapes during the day. This display is crucial for other vessels to recognize that the fishing vessel is engaged in fishing operations, allowing them to navigate safely and avoid potential collisions.

Displaying these lights helps other mariners understand not only that the vessel is fishing but also informs them of the type of fishing activity, which is vital for safe passage in areas where fishing vessels operate. The requirement for lights and shapes is designed to enhance safety on the water, as it communicates necessary information to nearby vessels concerning the fishing activities taking place.
