This museum has been preserving and interpreting the maritime history, especially that of California since 1995. The current fleet on exhibit includes the tug boat “Alma” that rescued sailors from the December 1941 Japanese attack on a Union Oil tanker off the coast of Morro Bay and the “Avalon,” one of two Deep Submergence Rescue Vehicles (DSRV) submarines designed to rescue crews of downed submarines. The museum is located at 1210 Embarcadero in Morro Bay.
