Memorial Day Launching Ceremony
Marinship chose a very fitting and stirring day for the launching of its fourth tanker - the S. S. Mascoma.
On this occasion - Memorial Day - in even greater need for the fulfilment of their obligation to Uncle Sam's fighting men was brought home to the throng of workers as they watched the huge tanker, destined to carry oil to the Allies, slide into Richardson Bay. The entire ceremony was keyed to the day, with the birth of a new ship and the honoring of the nation's hero dead jointly underlying the program.

He wrote : Here is SS Transchamplain (Ex USS Mascona) of Hudson Waterways Corp.
(also known as Seatrain Lines) while working cargo at Sand Island Terminal in Honolulu,
Hawaii. Diamond Head can be seen in backround. Photo was taken sometime in the early
1970's, I beleive. I worked aboard this vessel as Deck Cadet in 1974. She was running
between US West Coast, Hawaii, and Guam for Hudson Waterways at that time.
