Marine pilots are the professionals who carry out this work. They have great experience and technical knowledge of navigation and maneuvering of ships, as well as local peculiarities. This function is carried out on board ships to which the pilots are driven by means of boats which have special standards for the safe transshipment of the Pilotage.
