A CLASSIC Maldon landmark is celebrating a milestone anniversary this year. The steam tug ‘Brent’ celebrated her 75th birthday in March, decades after it was first named in 1946. Some steam tugs were used during the Second World War by the Ministry of War Transport, including in the D-Day landings and for naval work in ports around the country and abroad. In 1945 at Sunderland’s Pickersgill and Sons shipyard, TID 159 – one of 182 steam tugs built as part of the war effort – was launched too late. The vessel was sold in 1946 to the Port of London Authority, which named her ‘Brent’ and she was used to help maintain the River Thames as a navigable waterway.
