Unless my memory is playing tricks there was also No7 and No 8 Dredgers working, although I stand to be corrected.

Thank You for the info George, Iam sure there was an incident with one of them when a vessel went the wrong side and got caught up in the wires whilst dredging was being carried out on the stretch between the Furness Basin and Newport Bridge.
