When I was a wee lad my parents took us to Baltimore Harbour in West Cork Ireland for a day out away from the mundanety of Mallow.
While we were standing at the pier, there was a fishing boat alongside, bobbing against the attached Dunlop's ™ and dock- -lined to a mooring cleat.
My father, who knew a lot about boats and indeed the sea, remarked, that it was high tied, my dyslexia had not been diagnosed at the time, therefore, I was not aware of the water.
