I would like to reach or at least sail by the northernmost point in the UK. This is Out Stack, an uninhabited rock north of the island of Unst, Shetland, Scotland. It is possible to see Out Stack from the north coast of Unst, although getting there requires a four to five hour hike.
Wikitravel claims one can get to Out Stack by fishing boat, but it fails to identify where fishermen hang around.
I'm on Unst right now. Any tips on doing this?
