Coos Bay Mosquito Fleet
The Coos Bay Mosquito Fleet comprised numerous small steamboats and motor vessels which operated in the late 19th and early 20th centuries on Coos Bay, a large and mostly shallow harbor on the southwest coast of the U.S. state of Oregon, to the north of the Coquille River valley. Coos Bay is the major harbor on the west coast of the United States between San Francisco and the mouth of the Columbia River. Establishment of inland water routes Inland riverboats were used to navigate the bay and the several rivers flow that flow into it. Many of the passages were quite narrow, for example Beaver Slough was aptly named, as every night beavers built dams across the slough which had to be dismantled to allow the passage of ''Mud Hen''. Nat H. Lane and W.H. Troup, both steamboat captains from the Columbia River, began steamboat operations on Coos Bay in 1873. They built and operated ''Messenger'', doing business as the Coos Bay and Coquille Transportation Company.Wright, ed., ''Lewis & D ...

Steamboat Coos
A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. Steamboats sometimes use the prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'); however, these designations are most often used for steamships. The term ''steamboat'' is used to refer to smaller, insular, steam-powered boats working on lakes and rivers, particularly riverboats. As using steam became more reliable, steam power became applied to larger, ocean-going vessels. Background Limitations of the Newcomen steam engine Early steamboat designs used Newcomen steam engines. These engines were large, heavy, and produced little power, which resulted in an unfavorable power-to-weight ratio. The Newcomen engine also produced a reciprocating or rocking motion because it was designed for pumping. The piston stroke was caused by a water jet in the steam-filled cylinder, which condensed the steam, creating a vacuum, which in turn caus ...

Knee (construction)
In woodworking, a knee is a natural or cut, curved piece of wood. Knees, sometimes called ships knees, are a common form of bracing in boat building and occasionally in timber framing. A rafter, knee rafter in carpentry is a bent rafter used to gain head room in an attic. Strength characteristics Wood is a highly anisotropic material (its strength varies considerably with the direction of applied force, i.e. parallel, radial, or tangential to the grain). Because wood is strongest when loaded in tension or compression along the grain, the best knees are those in which the wood grain follows the bend. For a knee with relatively little bend, it may be possible to cut the knee out of a single straight-grained board and still achieve sufficient strength. However, with increasing bend this method becomes problematic since more and more of the knee is aligned across the grain and is therefore considerably weaker. A knee laid out this way might easily snap in two under hand pressure alon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rainbow (sternwheeler)
''Rainbow'' was a sternwheel steamboat that was operated in the Coos Bay region of Oregon from 1912 to 1923. ''Rainbow'' is sometimes referred to as a "launch", meaning a small steamboat. This vessel's name is sometimes seen as ''Rain-Bow''. Design, construction, and launch Shipbuilder Frank Lowe built ''Rainbow'' at Coos Bay, Oregon, Marshfield (Coos Bay), Oregon in 1912.Newell, Gordon R., ed., ''H.W. McCurdy Marine History of the Pacific Northwest'', Superior Publishing (1966), at pages 207 and 344. The steamer was launched on March 26, 1912, at 7:00 a.m. No formal launching ceremony was held, due to uncertainty of when during the day the launch would occur.''Coos Bay Times'', March 27, 1913, page 4, col. 2. ''Rainbow'' had been built for Captain Charles E. Edwards, of Allegany, Oregon. At the time of the launch, ''Rainbow'' had no engines, and to install the engines and otherwise prepare the vessel for service, was estimated, at the time of launch, to take about three week ...
