Bishop's Rock Lighthouse, Scilly Isles
In the hope that Alan Priddy can tell us what it is really like, I attach a map to show our European brothers and colonial cousins where it is. Also a photo of the Hanjangue Rock in the Eastern Isles of Scilly which is 19m high (or as us mariners say "Conspic.").
I ahve to say whenever I have been there the sea has always been very calm but I can imagine that it's a swine in a strong westerley.
