More from David Asprey

I have her as still UK flag and owned by "R W O'Reilly" since at least 4/2018. ON 722282, c/s MXSC6

Also seen operator named as "Vince O’Driscoll", based in Baltimore, Co Cork.

I worked for Costain & Blankevoort in 1970 on the river tees and had the pleasure of skippering her when she was brand new (Damen Pushycat 42) she then had a Caterpillar engine 240hp and was a a absolutely brilliant boat to handle.
On two occasions I have seen her, once on the Clyde and the latest sighting was four years ago slipped at Blyth.
There was a sister to Barracuda bay exact identical "Salmon Bay". I have tried to find the Salmon Bay but it seems there is no information anywhere about her.
