Thanks Caro. That was what I tried to do. I can get to the log pages, so it is possible to confirm that the log said that the position was east, not west of Greenwich, (ie that the Google Earth view is wrong for that specific day). What I hoped to do was to see what I entered for that page to make sure that I had not forgotten the E, or done something else wrong. It is not possible to see my own entries for that log page anymore as the ship is completed.
Hope this is clear.
Would it help if I collected together dates and log page addresses for some of the points that are wrong and put them into a message?
