1. Latitude/longitude, including for days in port, show representative decimal positions for each day, as calculated by the Old Weather project's analysis program. As such, they differ by varying amounts from the positions recorded, usually at noon, in the log pages. In addition, some latitudes/longitudes have been amended in edited logs for errors in the logs, for errors in identifying locations by the analysis program, or simply for greater accuracy. In all cases, refer to the log-page scans for the positions as originally recorded. Not all log pages contain this information and the ships' positions have therefore often been estimated.

2. Full account of any day is available by clicking on the link above that day. Groups of links refer to log book covers and introductory information; some may be blank.

(Maps prepared using Journey Plotter, developed by Maikel. The Plots can only be approximate. They are made by joining-up positions on successive days, and sometimes positions are not given. There will therefore be occasions when the ship appears to have travelled overland)
