Can you ID this Danzig cap?

[tonyco]

I picked this cap up at a flea market in Germany some 30 years ago. I have been able to identify the flag in the center of the wreath as that of the Free City of Danzig (1920 - 1939). Does anyone have any idea what vessel the cap may be associated with? Or, where I might turn for information?
Thanks for your help,
Tony

Paul, Thank you so much for your reply. You've given me a great lead to follow.
I spent some time in Ireland a couple of years ago. Terrific people and a beautiful country!
Thanks Again,
