RAF Bridlington.
I was at Leconfield with the helicopter resque squadron (228) in 1960 and we used to use the Bridlington launch for wet winching.
We lost a Whirlwind (S-55) which had an engine failure while hovering over the boat. The helicopter went in alongside the boat and the crew were immediatly picked up. At least one of them never got wet.
The Marine Craft unit guys lived in a house on the sea front and we used to stay there at weekends whilst sampling the local fare!!
So I would say that your dad had something to do with boats while he was in the RAF.
Happy days.
