Nice one Wolfgang, I must confess that I had visions of spending a Saturday down in the Central Libuary at Cardiff reasearching this with the "Admiralty Pilots".

On the "Stan Rogers Website" Click Here - This is found 64. Three Mile Rock -- "Mary Ellen Carter" -- Not known whether this is a real place or not, but such shipping hazards are plentiful.

As a caveat though :-
1/. Stan Rogers wrote more about Nova Scotia, though this does not signify.
2/. Local names and Charted Hazards may not be the same.

There are still many hazards which have no name untill some poor benighted navigator finds it the hard way.

Leaving, as did the "Richard Montgomery" on Grain Spit between the Medway and the London River, a very prominent marker.
