On December 11, 1952, the SS Hawaiian Rancher, a cargo vessel of 8,353 gross tons, was inbound in San Francisco Bay and proceeding to an anchorage. The MV Fernstream departed the north side of pier 22 at 6:52 a.m. and was outbound with a crew of 42 and 11 passengers proceeding to sea for Manila, Philippines. Fernstream was fully loaded with 6,378 tons of cargo that consisted of primarily soy beans; the balance being general cargo and mail. The weather was foggy with visibility less than a half mile; the sea calm. Both vessels were sounding regulation fog signals; their respective radars manned by competent personnel. It wasn't long before errors in judgment of course and speed were made and both vessels collided at 7:30 a.m. off Lime Point Lighthouse. The vessels collided at an angle of approximately 20 degrees. The port bow and stern of Hawaiian Rancher first came in contact with the portside of the Fernstream just abaft the bridge, damaging one of Fernstream's lifeboats and superstructure. It penetrated the hull at the after part of the engine room, damaging the watertight bulkhead to No. 4 hold. The bow of the Hawaiian Rancher withdrew from the hole in the Fernstream and within a few seconds Fernstream sank, all 53 were saved.
