What do you want to know about Bar boats.
I worked on 3: Barnstone, Barrage and Barcarole.
I was also the Buffer of the Laymoor, which was a more modern version of the Bar class. I finished my time as a PO BT1. When the Boom Defence and Marine Salvage Branch packed up in 1968 I bought myself out. I didn't fancy being in the Navy without Boomers
I hope that I can help you.
