Whoo! I thought I was lucky going fishing on a 28ft Trimaran!
My father was Navy (RANVR) WWII. He was British Naval Liason Officer (BNLO) stationed at Subic Bay with the US Navy. Before that he'd sit on islands with a radio, a Thompson submachine gun, and a US Colt .45 reporting Japanese movements. Dangerous stuff if caught! Different technology back then.
Where you serving as a submariner when photo taken?
