Alex McDonald
Staten Island NY
Alex McDonald was a small shipyard in Mariners Harbor. It was started before WWI and continued afterwards, until merging with Staten Island Shipbuilding in 1929 and later becoming the east end of the Bethlehem Steel shipyard. The yard was at 2855 Richmond Terrace, a once-busy stretch of industrial activities that is now a sprawling dump. I can find no record of the boats built by McDonald either before or after the war.
