Transparency taken from Gladstone Lock entrance showing the Blue Funnel Cargo Liner Perseus being held off the wall by the Rea Tug Maplegarth, and the tug looks as though it's quite an effort. Not sure of the date, so rather not guess!!
Many thanks Chris, I do remember the occasion as the authorities on the lock side were getting a bit anxious as the Tugs were having to hold her on the wall and the tide was vicious. Seemingly the warp men were a little busy elsewhere (possibly raising an elbow!) We think the ship must have been a bit early for them!!
