This is THV (‘Trinity House Vessel’) Galatea, the largest of Trinity House’s dedicated vessels keeping our seaways open. Lucky us – we got to work on board her for three days, making our film about ‘TH’s training scheme. Both ship and crew impress, highly. Galatea is constantly at sea – except on swift crew changeover days – checking that buoy lights are working, that buoys are in position, that their solar panels are charging the lights’ batteries OK, and that they’re free of the marine growth that encrusts them as they silently make the way safe for the thousands of ships operating around our coasts. She also maintains all the lighthouses for England, Wales, the Channel Islands and Gibraltar. Light vessels have to be cared for, too. But no keepers – it’s all run online from the Trinity House HQ in Harwich!
