This photo was taken, as I recall, on board one of those covered Coaxain's Boats.
This was just after i had completed a week end working in the Torpedo Shop on the Sub Tender USS Sperry or USS Nereus.
Another Reservist from my Submarine Reserve Unit, TM2(SS) Ruiz. I believe, snapped this photo. He was a photographer by trade, as I recall.
He took the photo as we were returning to shore from the tender, which was moored out in the water at Fort Roscrans, Ballast Point Submarine Base, San Diego, California.
