This investigation of methods used in Astronomical Navigation has been carried out by means of questionnaires completed by senior students at a few of our Navigation Schools. The data has been classified into fairly broad categories since some of it has been rather difficult to assess, due to incomplete information on such details as trading areas, which watch was being kept, and the actual time spent at sea during the year.
