It was an excellent tale Reg, and you don't need to tell a story. It is just that the beer must have a picture with an actual nautical theme. I can see I did not set the parameters accurately enough. A ship, sailor or dockyard, or even mermaid or whale might pass, but an iceberg might be pushing it a bit, because the connection is a bit more obtuse.
Let's open it up a bit and see how ingenious people can be then. Doom bar is in!
