(SP-647) -- later known as USS SP-647 -- was originally a motorboat used
by the San Francisco Bar Pilot's Association as a pilot boat. She was
leased by the Navy, and outfitted as an armed patrol craft, assigned to
patrol and protect San Francisco harbor. At war's end, she was returned
to the pilot's association. California, a 58' 2" motorboat, was built in
1910 at San Francisco, California, for local employment as a pilot boat.
She was leased from the San Francisco Bar Pilot's Association and
commissioned in the Navy as USS California (SP-647) on 28 April 1917.
