Moore Dry Dock and the Ship
Builders of the Estuary
waterfront in Oakland and Alameda provided an ideal location for
shipbuilders who, in turn, provided jobs for carpenters, caulkers,
sailmakers, riggers, rope makers and shipsmiths. As early as the 1860s,
shipwrights were building ferryboats at the Central Pacific Railroad
yards in West Oakland. By 1910, estuary shipbuilders included Hay &
Wright and Bethlehem Shipbuilding Corp. in Alameda, and Hanlon Shipyard
and Moore Dry Dock in Oakland.
Moore Dry Dock was the largest of the shipyards on the estuary. The
company first moved to the foot of Adeline St. in Oakland in 1909. Work
included building and repairing ships such as tankers, ferryboats and
dredges. Business was good, but it was the need for ships in World War I
that swelled the workforce to 12,000 men. In one day in 1919, three
tankers and three freighters were launched in one tide, setting a world
After the war, demand for new ships declined and work shifted to the
repair of ships in dry dock as well as production of structural steel
for buildings and bridges. Projects included building both the Park St.
and High St. bridges as well as structural elements for the Paramount
Theater and the cyclotron at UC Berkeley. The work force between the
world wars averaged around 2,000 workers.
World War II caused the next boom in shipbuilding. Moore Dry Dock
expanded dramatically, leasing additional land and building slips, steel
fabricating and machine shops, and worker housing. The workforce reached
a peak of 37,000 workers employed around the clock in 1943. Workers
welded literally miles of metal seams in the construction of 112 ships
between 1938 and the launch of the last sea-going vessel from Moore Dry
Dock in 1945. Moore Dry Dock closed in 1961.
The nature of shipping and shipbuilding has changed dramatically since
1945, and the impact has been felt on our estuary. A modern tanker can
be up to thirty times the size of a World War I vessel so that fewer
ships are carrying more cargo. Greatly improved navigational devices
prevent many of the accidents that formerly required dry dock repair of
ships. The cost of land and labor as well as environmental controls
protecting the waterfront make it difficult to compete for the small
amount of remaining shipbuilding business. Wars notwithstanding, it is
unlikely that this industry will return to our waterfront.
