The book is linked to the Institute's self-study scheme leading to a Harbour Master's Certificate. It explains the different responsibilities that vary between ports and shows, from the experience of Harbour Masters from different types of ports all over the world, examples of what new entrants to the industry may encounter. Different aspects of the role are examined, largely following the course of a vessel as it approaches port until she berths, including the commercial pressures that may be brought to bear. It is an ideal bridging course for those thinking of a career move ashore.
