A company representative ashore, usually a former master, who assists vessels in port with local knowledge, clearances, and operational support.
In practice
Under the ISM Code, the designated person ashore (DPA) is the primary safety and compliance contact, but port captains often act as a practical interface between the vessel and the shore organisation for operational matters. In some companies the port captain function is combined with the marine superintendent role, while in others a network of retained port agents serves the same purpose. On high-risk port calls — particularly in ports with shallow approach channels, strong tidal streams, or limited tug availability — the port captain may board the vessel to advise the master in person, supplementing the compulsory pilot's local knowledge with company-specific operational guidance.
Regulatory detail & full definition
A port captain is a shore-based company representative — almost always a former master with extensive local or regional experience — who assists the company's vessels during port calls. The port captain's role encompasses facilitating port clearances, liaising with port authorities, customs, and immigration, arranging agency services, coordinating husbanding of crew, and advising masters on local regulations, traffic management procedures, and any unusual conditions in the port or approach channel.
