I'm afraid Turbulent is incorrect when he states there is no weed in the pond at Eaton Park. He has, so far, been fortunate enough not to encounter any.
U147 was silent running at periscpe depth two weeks ago. It suddenly disappeared which caused considerable concern, considering it had only just returned to active service after a big salvage operation. When it did eventually surface it was running very slowly and then stoped near the side of the pond. The port prop. and kort nozzle were completely jammed with a very fibrous weed. The boat was returned to dry dock were the port motor/gearbox and speed controller were found to be faulty and needed total replacement. The boat has now been repaired and should sail this Sunday on it's next patrol.
