On reflection, the Wikepedia link will more than adequately inform Scott, wherever he may be.
I'll just add that notwithstanding the active interest in lifesaving based on Bamburgh under the auspices of the Duke of Northumberland in the previous century, the boat used by Grace Darling in the celebrated Forfarshire rescue of 1838 was a standard East Coast coble. You can see Bamburgh castle from the Farne Islands - on a good day, that is.
