The ALICE ROSS was a 70 foot motor passenger boat designed by Naval Architect L.H. Coolidge. She was built by Seattle City Light for Diablo Lake excursions to the new hydro-electric plant, which was built in 1935. She was a 300 passenger vessel, and was powered by a 175-horsepower Hull-Scott gasoline engine (p. 437). [Notes from Gordon Newell, ed., The H.W.
