The MV Chimacum is the third vessel of the Olympic-class auto ferries for the Washington State Ferries system. The ship was built by Vigor Industrial in Seattle, Washington and entered service on the Seattle–Bremerton route in 2017.
Funding for a third Olympic class was authorized in the Spring 2014 session of the Washington State Legislature and the keel laying and first weld took place on December 9, 2014.
The Chimacum has two car decks, a sun deck and a passenger deck.
She was christened on September 14, 2016 by Lynne Griffith, who at the time was serving as the head of the ferries system, the first woman to hold the office. The ceremony took place at the Vigor Industrial shipyard on Seattle's Harbor Island. She was delivered to Washington State Ferries on April 7, 2017, with her entry into service, replacing MV Klahowya, expected in the following months. She was forced into a three-day early temporary service on May 24 after The MV Kitsap, suffered a mechanical break down and all other vessels were in maintenance until the MV Kaleetan, could replace her on the Seattle–Bremerton run to finish Sea Trials and Training.
