Whaleback
] A whaleback was a type of cargo steamship of unusual design, with a hull that continuously curved above the waterline from vertical to horizontal. When fully loaded, only the rounded portion of the hull (the "whaleback" proper) could be seen above the waterline. With sides curved in towards the ends, it had a Spoon-shaped bow, spoon bow and a very convex upper deck. It was formerly used on the Great Lakes of Canada and the United States, notably for carrying grain or ore. The sole surviving ship of the "whaleback" design is the , which is docked in Superior, Wisconsin as a museum ship. The term developed in common usage in response to the ship's appearance when fully loaded. A total of 44 such vessels were constructed from 1887 to 1898. All but two were built initially as lake freighters for service on the Great Lakes. Six were built at Duluth, Minnesota; 33 were built at West Superior, Wisconsin; 2 at Brooklyn, New York; one at Everett, Washington; and one at Sunderland, Eng ...

Alexander McDougall (ship Designer)
Captain Alexander McDougall (March 15, 1845 – May 27, 1923) was a Scottish-born American seaman who built the whaleback style of cargo and excursion ship. In 1880, he designed a ship that he felt could withstand the worst lake water and carry the greatest cargo in the least depth of water. In 1917 he founded McDougall Duluth Shipbuilding Company to build World War I ships. Early life McDougall was born on March 15, 1845, on the island of Islay, Scotland. He was the eldest son of parents Dugald and Ellen McDougall. In 1854, when McDougall was ten, he emigrated with his parents to the Canadian-Scots settlement of Nottawa, Ontario, now part of Collingwood. In 1862, at the age of seventeen, McDougall shipped out on the Great Lakes after limited schooling. He had time to pursue his hobby of designing ships of steel, and his experience with the violent storms of the Great Lakes prompted him to design the whaleback. Whaleback McDougall built his first whaleback barge on his property ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Freighter
Lake freighters, or lakers, are bulk carrier vessels that operate on the Great Lakes of North America. These vessels are traditionally called boats, although classified as ships. Since the late 19th century, lakers have carried bulk cargoes of materials such as limestone, iron ore, grain, coal, or salt from the mines and fields of the upper Great Lakes to the populous industrial areas farther east. The 63 commercial ports handled 173 million tons of cargo in 2006. Because of winter ice on the lakes, the navigation season is not usually year-round. The Soo Locks and Welland Canal close from mid-January to late March, when most boats are laid up for maintenance. Crew members spend these months ashore. Depending on their application, lakers may also be referred to by their types, such as ''oreboats'' or ''ironboats'' (primarily for iron ore), ''straight deckers'' (no self-unloading gear), ''bulkers'' (carry bulk cargo), ''sternenders'' (all cabins aft), ''self unloaders'' (with sel ...

Turret Deck Ship
A turret deck ship is a type of merchant ship with an unusual hull, designed and built in the late 19th and early 20th centuries. The hulls of turret deck vessels were rounded and stepped inward above their waterlines. This gave some advantages in strength and allowed them to pay lower canal tolls under tonnage measurement rules then in effect. The type ceased to be built after those rules changed. There are no surviving examples. Development Turret deck ships were inspired by the visit of the US whaleback vessel to Liverpool in 1891. Like others of the type, ''Wetmore'' had a hull in the form of a flattened cigar, with a continuous curve above the waterline to where the sides met amidships.OakleyWhaleback freighter ''Charles W. Wetmore'' arrives in Everett on December 21, 1891 The superstructure atop the hull was in round or oval "turrets", so named because of their resemblance to gunhouses on contemporary warships.

Queen Of The Lakes
''Queen of the Lakes'' is the unofficial but widely recognized title given to the longest vessel active on the Great Lakes of the United States and Canada. A number of vessels, mostly lake freighters, have been known by the title. History of name ''Queen of the Lakes'' has been used as the name of three vessels that sailed on the Great Lakes, but none was the longest on the lakes at the time. The first was a three-masted Canadian schooner built in 1853 as ''Robert Taylor'', measuring . It was renamed ''Queen of the Lakes'' sometime before 1864. She sank off Sodus Point, New York on November 28, 1906. The second was a propeller-driven vessel launched in Cleveland, Ohio, on May 12, 1853, measuring . She was lost to fire in port on June 17, 1869. The third was a small side-wheel steamer built in Wyandotte, Michigan in 1872, measuring . While anchored near South Manitou Island she caught fire and burned in 1898. The iron hull was later scrapped. The title has also been bestowed upon ...

Barge
Barge nowadays generally refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but nowadays most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges. History of the barge Etymology "Barge" is attested from 1300, from Old French ''barge'', from Vulgar Latin ''barga''. The word originally could refer to any small boat; the modern meaning arose around 1480. ''Bark'' "small ship" is attested from 1420, from Old French ''barque'', from Vulgar Latin ''barca'' (400 AD). The more precise meaning of Barque as "three-masted sailing vessel" arose in the 17th century, and often takes the French spelling for disambiguation. Both are probably derived from the Latin ''barica'', from Greek ''baris'' "Egyptian boat", from Coptic ''bari'' "small boat", hieroglyphic Egyptian D58-G29-M17-M17-D21-P1 and similar ''b ...

Strake
On a vessel's hull, a strake is a longitudinal course of planking or plating which runs from the boat's stempost (at the bows) to the sternpost or transom (at the rear). The garboard strakes are the two immediately adjacent to the keel on each side. The word derives from traditional wooden boat building methods, used in both carvel and clinker construction. In a metal ship, a strake is a course of plating. Construction In small boats strakes may be single continuous pieces of wood. In larger wooden vessels strakes typically comprise several planks which are either scarfed, or butt-jointed and reinforced with a butt block. Where the transverse sections of the vessel's shape are fuller, the strakes are wider; they taper toward the ends. In a riveted steel ship, the strakes were usually lapped and joggled (one strake given projections to match indentions in the one adjoining), but where a smoother finish was sought they might be riveted on a butt strap, though this w ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Donkey Boiler
There have been a vast number of designs of steam boiler, particularly towards the end of the 19th century when the technology was evolving rapidly. A great many of these took the names of their originators or primary manufacturers, rather than a more descriptive name. Some large manufacturers also made boilers of several types. Accordingly, it is difficult to identify their technical aspects from merely their name. This list presents these known, notable names and a brief description of their main characteristics. See also * Glossary of boiler terminology Boilers for generating steam or hot water have been designed in countless shapes, sizes and configurations. An extensive terminology has evolved to describe their common features. This glossary provides definitions for these terms. Terms which re ...
