I once decided to hug the Western coast of England/Scotland, entering into St. Georges channel, through the Irish Sea, out past the Mull of Kintyre, and then up through Sea of the Hebrides and through the Minch, exiting past Loch Ewe.
In 1943.
Needless to say, I didn't make it.
I'm doing it again now, in 1940. So far, much easier and much more lucrative. Just passed the Mull of Kintyre, and I am already out of eels. I may abort out to the Western approaches, then swing around the north to get back to Bill's haven.
