This paper describes the growing automobile congestion within the Golden Gate Corridor and reviews an alternative means of public transportation through the use of buses and ferries. The paper outlines the planning and design criteria used in the selection of an optimum vessel and related terminal facilities. Three new Spaulding Class 165 foot, 750 passenger, vessels are presently under construction. These vessels will be all aluminum with a 25 knot power package consisting of gas turbine engines and waterjet pumps. Two modern marine passenger terminals have also been designed, with construction of one already completed.
