MV Napa (previously MV Snohomish) is a passenger-only fast ferry operated by Golden Gate Ferries. The vessel is named after Napa County, one of the member counties of the Golden Gate Bridge, Highway and Transportation District. Napa was purchased from Washington State Ferries (along with MV Chinook) and will enter service with Golden Gate Transit after a refit. The Napa entered service as a substitute for MV Del Norte when that vessel began undergoing an engine replacement in June 2009. After Chinook returned from its refit, Napa went in for a full refitting.
