In a traffic separation scheme, vessels following the designated lane have priority and other traffic should not impede their passage. A vessel engaged in fishing must not block or hinder a vessel that is proceeding along a lane, especially when there is a risk of collision. With the PDV in the lane and a VEI vessel appearing on the port bow, the safest and most appropriate action is to maintain your course and speed, while giving the VEI an opportunity to maneuver clear if possible and keeping a close watch for any change that might bring you alongside or into collision. This approach minimizes unnecessary maneuvering within the lane while still preserving safety; you’re ready to adjust promptly if the VEI does not clear.

Stopping in the lane would be inappropriate and dangerous. Passing on the starboard side isn’t warranted unless the VEI’s maneuvering necessitates it, and it could complicate traffic within the TSS. While it’s true that a VEI should not impede vessels following a traffic lane, relying on that rule alone without taking timely action when ROC exists would be unsafe; hence the prudent choice is to keep your course and speed and monitor carefully, ready to take action if needed.
