Hog chains were a technological device that permitted river boats to have lightly built hulls so they could travel in shallow water.
It was advantageous for river vessels to operate in very shallow water, so that work could be done at all seasons and in areas that lacked deeper rivers. This required flat-bottomed boats with lightly built hulls. However, the hulls tended to bend out of shape over time, particularly with sternwheelers, which had heavy components at stern (the sternwheel) and also towards the bow (the boilers). [1] If the boat hull became bowed upwards in the middle, this was called "hogging". If the boat bowed down in the middle, this was called "sagging".
To forestall hogging and sagging, since about 1850, the hulls of wooden river boats were held in shape by a system of wire trusses, called "hog chains". [1] These were not chains at all, but rather iron rods 1 to 2.5 inches (25 to 64 mm) in diameter, which ran from strong points in the hull to vertical timbers, called "hog posts", which looked like masts, rising above the hull. [1] Tension on the hog chains was adjusted through the use of turnbuckles. [1] Generally the hog posts which carried the chains did not rise above the cabins on Mississippi River-style steamers. [1] This was not the case with steamboats designed in the Pacific Northwest style, where the hogposts were often clearly visible rising above the superstructure.
Should the hog-chains break, the hull would come out of tension, and start sagging on the ends. This was called being "hogged". In some cases the sagging on the ends would be so great that a boat's hull would break in half. [1] Accidents such as running aground were the kind of things that could cause hog-chains to break. [1]
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 or PS ; however, these designations are most often used for steamships.
A riverboat is a watercraft designed for inland navigation on lakes, rivers, and artificial waterways. They are generally equipped and outfitted as work boats in one of the carrying trades, for freight or people transport, including luxury units constructed for entertainment enterprises, such as lake or harbour tour boats. As larger water craft, virtually all riverboats are especially designed and constructed, or alternatively, constructed with special-purpose features that optimize them as riverine or lake service craft, for instance, dredgers, survey boats, fisheries management craft, fireboats and law enforcement patrol craft.
This glossary of nautical terms is an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water. Some remain current, while many date from the 17th to 19th centuries. The word nautical derives from the Latin nauticus, from Greek nautikos, from nautēs: "sailor", from naus: "ship".
Clinker-built is a method of boat building in which the edges of hull planks overlap each other. Where necessary in larger craft, shorter planks can be joined end to end, creating a longer strake or hull plank.
Bonnington was a sternwheel steamboat that ran on the Arrow Lakes in British Columbia from 1911 to 1931. Bonnington and two sisterships were the largest sternwheelers ever built in British Columbia. Bonnington was partially dismantled in the 1950s, and later sank, making the vessel the largest freshwater wreck site in British Columbia.
Many steamboats operated on the Columbia River and its tributaries, in the Pacific Northwest region of North America, from about 1850 to 1981. Major tributaries of the Columbia that formed steamboat routes included the Willamette and Snake rivers. Navigation was impractical between the Snake River and the Canada–US border, due to several rapids, but steamboats also operated along the Wenatchee Reach of the Columbia, in northern Washington, and on the Arrow Lakes of southern British Columbia.
The Willamette River flows northwards down the Willamette Valley until it meets the Columbia River at a point 101 miles from the Pacific Ocean, in the U.S. state of Oregon.
The Colonel Wright was the first steamboat to operate on the Columbia River above The Dalles in the parts of the Oregon Country that later became the U.S. states of Oregon, Washington and Idaho. She was the first steamboat to run on the Snake River. She was named after Colonel George Wright, an army commander in the Indian Wars in the Oregon Country in the 1850s. She was generally called the Wright during her operating career.
The sidewheeler Idaho was a steamboat that ran on the Columbia River and Puget Sound from 1860 to 1898. There is some confusion as to the origins of the name; many historians have proposed it is the inspiration for the name of the State of Idaho. Considerable doubt has been cast on this due to the fact that it is unclear if the boat was named before or after the idea of 'Idaho' as a territory name was proposed. John Ruckel also allegedly stated he had named the boat after a Native American term meaning 'Gem of the Mountains' he got from a mining friend from what is now Colorado territory. This steamer should not be confused with the many other vessels of the same name, including the sternwheeler Idaho built in 1903 for service on Lake Coeur d'Alene and the steamship Idaho of the Pacific Coast Steamship Line which sank near Port Townsend, Washington.
The Rossland was a sternwheel steamboat that ran on the Arrow Lakes in British Columbia. It was named after Rossland, British Columbia, once a prosperous mining town in the region.
Lytton was a sternwheel steamboat that ran on the Arrow Lakes and the Columbia River in southeastern British Columbia and northeastern Washington from 1890 to 1904.
Columbia was a sternwheel steamboat that ran on the Arrow Lakes in British Columbia from 1891 to 1894. Columbia should be distinguished from the many other vessels with the same or similar names, including in particular the propeller-driven steamboat Columbia that ran on the Arrow Lakes for many years.
The Enterprise was an early steamboat operating on the Willamette River in Oregon and also one of the first to operate on the Fraser River in British Columbia. This vessel should not be confused with the many other vessels, some of similar design, also named Enterprise. In earlier times, this vessel was sometimes called Tom Wright's Enterprise after one of her captains, the famous Tom Wright.
From 1886 to 1920, steamboats ran on the upper reaches of the Columbia and Kootenay in the Rocky Mountain Trench, in western North America. The circumstances of the rivers in the area, and the construction of transcontinental railways across the trench from east to west made steamboat navigation possible.
A chain boat, chain tug or chain-ship was a type of river craft, used in the second half of the 19th century and first half of the 20th century on many European rivers, that made use of a steel chain laid along the riverbed for its propulsion. The chain was engaged using a steam engine mounted on board and enabled the boat to tow a string of barges. In Germany, such a boat was variously referred to as a Kettenschleppschiff, Kettenschlepper, Kettendampfer or Kettenschiff and in France as a toueur.
Far West was a shallow draft sternwheel steamboat plying the upper Missouri and Yellowstone Rivers in the Dakota and Montana Territories, in the years from 1870 to 1883. By being involved in historic events in the Indian Wars of the western frontier, the Far West became an iconic symbol of the shallow draft steamboat plying the upper Missouri and Yellowstone Rivers in the era before railroads dominated transport in these areas.
Pomona was a steamboat which operated on the Willamette, Columbia and Cowlitz rivers from 1898 to 1940. Pomona was specially designed to operate in low water conditions such as typically prevailed in the summer months in Oregon. Pomona was one of the few steamers that could regularly navigate to Corvallis, Oregon, which was the practical head of navigation on the Willamette. In 1926, Pomona was substantially rebuilt, and served afterwards as a towboat. In 1940, Pomona was converted into an unpowered floating storehouse.
Grahamona was a sternwheel steamboat built in 1912 for the Oregon City Transportation Company, commonly known as the Yellow Stack Line. Grahamona was specially designed to serve on the shallow waters of the upper Willamette River. It was one of the largest steamboats ever to operate on the upper Willamette. In 1920, Grahamona was sold and the name was changed to Northwestern. In 1939, the vessel was sold again, and transferred to Alaska for service on the Kuskokwim River.
Mascot was a sternwheel-driven steamboat built in 1890 which operated primarily on a route running from Portland, Oregon down the Willamette and Columbia rivers to points on the Lewis and Lake rivers. Points served included the town of Woodland, Washington, on the main branch of the Lewis, and La Center, Washington on the east fork.
Chester was a shallow draft steamboat built in 1897 that ran until 1917, mostly on the Cowlitz River in southwestern Washington.
