Hello, I'm new on here. TS Thunderer was the former MTB 624 - a WWII Type D Fairmile motor torpedo boat with 4 American Packard marinised 1250 hp petrol engines. There were four screws. I think that she had a Viking funeral in Aberystwyth harbour. When she was sold in 1965, the wooden hull had rotted through and the people who bought her set her on fire at low tide at the centre of the harbour thinking that fire was the easiest way to separate the scrap metal from the wood. She had a distinguished wartime career and was formative in the lives of so many young people in Aberystwyth from 1946/47 to 1964. A long time ago, I was one of those young people.
