I read your message re the Lightening Masters.
You mean Captain Bramley. He was the regular Master on the Serenia.
A very dour personality until you got to know him better.
A Geordie through and through came from Ponteland.
Other Masters you have missed out Stan Owston who was normally on
Naticina. Bill Snowden served on Drupa, but was only on lightening ships
for a number of years.
As the shipping agent in Liverpool I used to meet these captains regularly.
