I used Google Earth to plan our trip to Southampton in the UK which never materialized. When a friend asked us to help him plan a circumnavigation of Ireland, I returned to Google Earth to work out the distances around the west coast with which our friend is unfamiliar. This way I could point out the places where there's nowhere to find shelter for big enough distances to worry about the weather. I found it to be really easy but I forgot to get a screengrab when it was all done, so I'll have to do it again. In the meantime, here it is for reference. NOT FOR Navigation. The miles really add up when you have to go in and out into anchorages and harbours.
