Ship pilot dispatchers coordinate ships entering or leaving port. They write orders showing name of ship, berth, tugboat company, and time of arrival or departure, and notify the maritime pilot of assignment. They obtain receipts of pilotage from the pilot upon return from ship. Ship pilot dispatchers also record charges on receipt, using tariff book as guide, compile reports of activities, such as number of ships piloted and charges made, and keep records of ships entering port, showing owner, name of ship, displacement tonnage, agent, and country of registration.
