I wasn’t sure what you meant. I was thinking about the “traffic lights” in Japan. For example in Yokohama the lights on the end of some breakwaters that flash "I’, “O” or “F” for Inbound, outbound (large ships) or free (for small coasters). I’d think if a ship was to violate those signals it would be contrary to Rule 2.
I do recall one of the pilots in Germany mentioning a requirement for smaller vessels to stay clear.
Professional mariners, military and civilian, will find this book to be an invaluable reference in understanding the rules of the road and the role these rules play in managing the risk of collision.
The author provides a thorough commentary on the rules and an analysis of collision cases involving abuse of the rules. Maritime attorneys and judges will find the book continues to be an indispensable reference on collision law as Craig Allen provides a mariner’s insight into how the rules apply in context and their application by the courts and administrative tribunals.
This new edition completely revises chapters on the rules pertaining to good seamanship and special circumstances and on restricted visibility, and it vastly expands coverage of the narrow channel rule, traffic separation schemes, and the application of the rules to high-speed craft. It also extensively revises materials on the lookout and risk of collision responsibilities to update coverage on radar and ARPA and to address new technologies, such as integrated bridge systems, automatic identification systems, voyage data recorders and the increasingly active role of VTS.
The first update in ten years, the eighth edition upholds and even surpasses the standards set over the past sixty years of the guide’s publication.
Mine is the 6th Edition.
