I think you will find that an Air Sea Rescue Launch was based at Bridlington.
Their shore based HQ would probably have been called RAF Bridlington.
I remember seeing the launch as a small boy around 1957.It stood out as the most glamorous boat in the harbour. I thought what a terrific job it would be to sail as part of the crew.By the time I actually joined the RAF there were no vacancies in the marine branch.
