Roy There would have been no Trinity House pilotage involvement in the visit. The Trinity House vessel in question would have been the Trinity House buoy yacht Irene. The Trinity yacht traditionally preceded the Royal Yacht and still does today the most recent example being in 2005 when the Trinity House vessel Patricia preceded HMS Endurance during the Trafalgar Fleet Review. Normally and prior to the Pilotage Act 1987 Trinity House vessels did not take pilots in areas where TH had responsibility for buoyage. Buoyage in the Humber was the responsibility of the Humber Conservancy Board. However it would seem likely that Irene would have taken a Humber Pilot from the pilot cutter at Spurn Point. There has been a number of changes in the way the Humber Pilots were organised over the years and a recent reorganisation would have meant the effective end of any pilotage records. Not sure about Lincolnshire newspapers. Hope this helps. Andy Adams
