Enclosed Dry Dock Opened on U.S. West Coast
Bay Ship & Yacht Co., an American service, refit and new construction yards for superyachts and commercial vessels, recently expanded its capacity and capabilities by unveiling a new covered dry dock that accommodates vessels displacing up to 6,300-long tons with a maximum beam of 76 feet. Currently the only dry dock on the West Coast to be fully enclosed by a retractable roof, this new high-tech facility on San Francisco Bay is a conversion of the submersible Hughes Mining Barge (HMB-1), which played a role in a covert Cold War operation. According to CIA documents declassified in 2012, the HMB-1 was built in the 1970s by the U.S.
