I was periodically hurled off the back of one of these at Mount Batten for the dreaded Sea Survival drills. In an effort to replicate the confusion of a helicopter ditching, the engines would be wound up to create a huge frothy plume at the stern, into which I was required to jump, without of course letting go of the dinghy (which strangely never had a serviceable Gas canister during training).
I had a good friend (sadly now passed away) who had served on this type of craft during the war. He was awarded the DSO (Distinguished Service Order) for rescuing downed allied airmen from France via the French resistance movement. CPO Billy Webb DSO, RN. was a one off type of bloke who also spent a lot of his time as a prison warder and was appalled at the way the prison service was going. He was of the old school and thought that criminals should be punished for their activities. In the end he was glad when retirement time came and he left the prison service. He then threw himself into running our branch of the RN Association. It was a sad day when Billy died. He was a real character and was invited to the USA every year by the "Downed Airmen's Association" of that country. They miss him too. Oh yes, he also used to join me on trips to Germany every year and we were great pals of the German Naval Association, they loved "Der Billy" too. He was that kind of man... Just remembered, Billy sent his DSO to be re-ribboned through a reputable Liverpool firm. The medal was lost in the post and Billy had to make do with a replica afterwards. Obviously some low life had nicked the medal in the post. He said it wasn't the same afterwards because he had been presented with the medal by King George VI. I keep looking on E-bay to see if someone is selling Billy's medal. I also wonder if reputable medal dealers check up on sellers.
