This report presents the results of a preliminary investigation of piloting practices on board U.S. vessels entering a number of ports in this country. Major goals of this investigation were the assessment of the feasibility of obtaining data which is useful for identifying pilots sources of information, studying the manner in which this information is processed, and determining how the information and its processing relate to the pilots commands. Thirteen transits, representing more than eighty-five hours of on-bridge time, were made in five different ports and waterways for the purpose of collecting data. Two data collection procedures were used. The first involved non-structured interviews conducted in a conversational manner with the pilot while he conned the vessel. The second method involved having the pilot think out loud while performing his piloting tasks. Audio and video recordings were made during the transits. The transcripts of these recordings contain detailed information about pilotage practices, procedures, and problems. The verbal protocol collected by the second method was analyzed in a limited way to test the techniques potential value for future studies.
