Vigor Shipyards was founded in 1916 as the William H. Todd Corporation through the merger of Robins Dry Dock & Repair Company of Erie Basin, Brooklyn, New York, the Tietjen & Long Dry Dock Company of Hoboken, New Jersey, and the Seattle Construction and Dry Dock Company. The Seattle shipyard could trace its history back to 1882, when Robert Moran opened a marine repair shop at Yesler's Wharf. This shop became the Moran Brothers Shipyard in 1906 and the Seattle Construction & Dry Dock Company at the end of 1911.
Vigor has performed building and maintenance work for, among others, the U.S. and Royal Australian Navies, the United States Coast Guard, and the Washington State Ferries. Its headquarters and operations are on Harbor Island at the mouth of Seattle's Duwamish Waterway.
The 105-foot (32 m)-long hull of Disneyland's Mark Twain Riverboat was built at Todd Shipyards in San Pedro, California in 1955.
In February 2011, Vigor Industrial purchased Todd for $130 million.[1] This included the Seattle, Everett and Bremerton operations.
