What color combination represents a fishing vessel under the Navigation Rules?

The correct color combination representing a fishing vessel under the Navigation Rules is red and white. This identification allows other vessels to recognize that they are encountering a fishing boat, which may be engaged in tasks such as netting or other forms of fishing.

In practice, fishing vessels display one or more vertical white lights when fishing at night, along with the red light to indicate their activity. This specific color pattern is essential for ensuring safety on the water by informing other mariners of the fishing vessel's status. Proper recognition of these light combinations helps prevent potential collisions and ensures that all vessels can navigate waterways safely.

The other color combinations do not correspond to the identification of fishing vessels according to the Navigation Rules, making them not applicable in this context. Understanding these visual signals is vital for mariners to comply with navigational conventions and maintain safety on the water.
