Years ago I went to do a job on a ship in Manchester docks, we set of down the Ship Canal heading for the Clyde, assisted by two tugboats. One tug broke down and the other was dispatched to help a vessel in trouble. Our ship continued on its own, after side-swiping another vessel and the bank they moored up at Barton Lock, having decided all was not well. Next morning, having arranged for a diver, he investigated and, on surfacing, he held up a handful of grease and reported that it came from where the starboard rudder should be. A month later, after the ship had been assisted to dry dock and a new rudder fitted, we set off again for Dumbarton.
The crew, with the help of a River Clyde pilot, managed to dock stern first at the shipyard, an amazing operation to watch as they managed it without tug assistance (the Clyde tug crews were on strike) took over an hour. I was told that when the pilot came on board he was offered a drink, "Not now he replied, lets get on with it". When the docking was finally successful he said "Now, I will take a whisky" down in one.
