What visual signal is used during the day for a vessel engaged in fishing when it is over 150m and restricts maneuverability?

The visual signal used during the day for a vessel engaged in fishing that exceeds 150 meters and restricts maneuverability is represented by two black cones with their apexes touching. This signal is standardized under maritime navigation rules to ensure that other vessels understand the specific operational status of the fishing vessel.

The use of two black cones, positioned with their apexes touching, clearly communicates that the vessel’s ability to maneuver is limited, thus alerting nearby vessels to exercise caution and maintain a safe distance. This is especially important in busy waterways, where understanding the signals of larger vessels can prevent collisions and ensure safe navigation.

The other options represent different visual signals designated for various circumstances at sea, but none correspond to the specific scenario of a fishing vessel over 150 meters in length and restricted in maneuverability. Having a consistent signaling system helps maintain safety and awareness in marine traffic.
