What dayshape must be shown by a vessel over 20 meters fishing which has gear extending more than 150 meters horizontally outward from it?

For a vessel over 20 meters in length that is engaged in fishing and has gear extending more than 150 meters horizontally from its sides, it is required to display a dayshape that clearly indicates its activity. The correct dayshape in this case is one black ball.

This signal serves to alert other vessels in the area that the fishing vessel is not only operational but also has fishing gear deployed. The single black ball indicates that it is engaged in fishing and that vessels should exercise caution when navigating in proximity to it, as the extended fishing gear could pose a danger if another vessel were to approach too closely.

The requirement for displaying a single black ball applies specifically to vessels using certain types of fishing gear, and it is a key aspect of maintaining safe navigation on the water. Understanding this regulation is essential for compliance and for ensuring the safety of all vessels operating in the vicinity of fishing activities.
