Once again...thank you all very much. The Glasgow is a real education. I've never heard of the two different logs before (love the names!) and this is the first time that I've noted stars being used to find position. I did wonder if it was a teaching exercise - but they do note those sessions as 'teaching' so I think this is just a very exacting ship?
I guess it becomes almost like second nature, but what with putting clocks on by a few minutes twice a day, using the stars as a guide, sorting out log deviations, there's a fair bit of territory to cover....never a dull moment?
