Abstract

This report summarizes inspection of corrosion and salt damage on the National Historical Landmark ferryboat Eureka, built in 1890 and displayed at the San Francisco Maritime National Historic Park of the U.S. National Park Service (NPS). The USDA Forest Service, Forest Products Laboratory (FPL) was contacted by the NPS because of concerns about white “corrosion products” that were forming on metal bolts in the bilge of the Eureka. Photographs shared by NPS showed signs of salt damage on the wood in addition to corroded bolts. As a result of conversations between FPL and NPS, an inspection was conducted. This report summarizes the findings of the inspection and gives recommendations that can be used to preserve the Eureka and possible actions to take during the next dry-docking of the ship.
