was the largest motor passenger vessel built to that date on the Pacific Coast. She was long (150') and narrow (18' beam), with a clipper bow and bowsprit. She had three gasoline engines connected to a single shaft. She could accommodate 50 passengers on the Portland-Tillamook route but had difficulty on the run and only served in the summer. She was called up by the navy to function as a patrol boat in the First World War. After the war, Bay Ocean was sold to Crowley Launch and Tug Co., of San Francisco. cannery tender Susan E. Elmore entering Tillamook Bay steamers Harrison and Susan E. Elmore at dock in Tillamook Last operations Mosquito fleet operations in the Coos Bay area and Coquille River valley continued up into the 1930s, due to the lack of good roads and other more modern transportation in these areas. As possibly the extreme example, the small (14 tons) gasoline-propeller Welcome, built 1919, was on the run up the Coos River from Marshfield to Allegany until 1948. Steamboat graveyards When steamboat service ended on the Coquille, at least three steamers, Myrtle, Telegraph, and Dora were all beached on the river near Bandon. The Mary D. Hume, built in 1881, is still largely intact, lying on the shore at Gold Beach, Oregon. The wreck itself is on the National Register of Historic Places. The steam ferry Roosevelt, which used to run on Coos Bay, was photographed abandoned near Marshfield in 1941. wreck of Roosevelt, steam ferry, near Marshfield List of vessels A large number of boats of all types were built on these waters, powered by various means, including steam, gasoline, and diesel engines. This index will attempt to track only vessels over 30 tons built before 1920, with exceptions where a vessel appears to be of more interest, due to an available on-line image or otherwise.
