(GeekWire Photo / Kurt Schlosser)The sun is setting on Washington state’s aging diesel-powered ferry fleet as work begins on new hybrid-electric vessels. Eastern Shipbuilding Group in Panama City, Fla., has started building the state’s first new ferry since the Suquamish launched in 2018. Washington State Ferries is the biggest contributor to greenhouse gases among state agencies. In 2019, the state struck a deal with Vigor, a Seattle shipyard, to build up to five hybrid-electric ferries, with the first due within three years. Negotiations between Washington State Ferries and Vigor over price and contract terms broke down, and the state ultimately relaunched a competitive bid for the project.
