I served on a small tug 'Corunna' in Leith during the Port re-development in 1965. She was owned by the now defunct 'Britannia Dredging'. I believe she was originally a Customs launch, twin screw 'Glennifer' diesels. After the contract she went back south to Shoreham, anyone know what happened after that. Also on the job was the Dutch bucket dredger 'Goliath' (steam) and the motor hopper 'Noviomagum'
