WHAT INFORMATION DO RIVER PILOTS USE?

This paper describes the results of a task analysis of pilot information usage on the Rotterdam waterways. The task analysis consisted of two parts: 1. Eleven trips on board ships going from the pilot station outside the Hook of Holland and vice versa; 2. Paper and pencil tasks given to seven pilots who had also cooperated during the trips. Based on theoretical notions of preprogrammed and feedback control, the references pilots use to compare the ship's movements against were investigated. The results clearly supported a notion of feedback control: pilots use landmarks such as pile moorings for initiating course changes, and they use buoys and leading lines consisting of two leading lights (at sea) for checking course changes. On the river, course changes are checked by taking bearings in order to maintain a safe distance to other ships and the river bank.
