The crew aboard Crowley Maritime Corporation’s tugboat Guard recently performed a heroic rescue of a man who was struggling to stay afloat in the waters outside of San Francisco Bay. The rescue took place during the early morning hours of Wednesday, October 31, while the tugboat was standing by outside the Golden Gate Bridge, waiting to escort a tanker into San Francisco Bay’s anchorage. Crowley’s Perry Overton, captain of the Guard, noticed the man treading water a little more than a mile and a half from the bridge.
