|127k||Ex-YSD-14 in operation as USACE Raccoon, collecting debris on San Francisco Bay. The San Francisco District US Army Corps of Engineers has had her in service since 1960 in the SF Bay and Tributaries as a Hazard to Navigation Drift Collector. The bow was modified in 1962 to accommodate 3 new debris nets 20' wide that each can lift 18 tons of debris during patrols.
It should be noted that the Raccoon's hull has been entirely replaced and is now on at least its fourth set of engines. The last shipyard modifications included adding Thordon Sealed shaft seals, new shafts, as well as many electrical and hydraulic upgrades. The Bucyrus Erie excavator is fixed to the vessel and has a newly rebuilt Pierce Pacific OR 3 stage knuckle boom crane that is designed with a tree and log handling grapple.
