Alden Rowing
Alden Rowing manufactures sliding-seat rowing boats. Their original product, the Alden Ocean Shell, was designed in (sources differ) 1970 or 1971. Traditional shell designs use high aspect ratio hulls, with long waterline with minimum beam, that emphasize racing performance at the cost of stability. These types of boats are only usable on flat water. Alden, however, specializes in shorter, beamier, highly stable designs which are suitable for rowing in open water, where swells are commonly encountered. As of 2004, Alden had sold 25,000 shells. History The original Alden Ocean Shell was designed by Arthur E. Martin, a naval architect, trained at Webb Institute. Martin had begun experimenting with fiberglass as a boatbuilding material in the 1960s. His first design, a kayak, was developed in 1966. Over the next few years, he added a sliding seat and a deck to shed water; this evolved into the Alden Ocean Shell by 1970. Martin Marine was formed in 1971, located in Cohasset, ...

Racing Shell
In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ''shell'') is an extremely narrow, and often comparatively long, rowing boat specifically designed for racing or exercise. It is outfitted with long oars, outriggers to hold the oarlocks away from the boat, and sliding seats. The boat's long length and semicircular cross-section reduce drag to a minimum. This makes the boat both fast and unstable. It must be balanced by the rowers to avoid tipping. Being able to balance – or "set" – the boat while putting maximum effort into the oars is therefore an essential skill of sport rowing. History The racing shell evolved from the simple working rowboat. Boats with longer hulls and narrower in beam were developed in the early 19th century specifically for team racing. These dedicated boats were the first boats that could be called racing shells, and they evolved into the highly specialized forms used today. Riggers A narrower boat provides a sharper ...

Load Path Analysis
Load path analysis is a technique of mechanical and structural engineering used to determine the path of maximum stress in a non-uniform load-bearing member in response to an applied load. Load path analysis can be used to minimize the material needed in the load-bearing member to support the design load. Load path analysis may be performed using the concept of a load transfer index, U*. In a structure, the main portion of the load is transferred through the stiffest route. The U* index represents the internal stiffness of every point within the structure. Consequently, the line connecting the highest U* values is the main load path. In other words, the main load path is the ridge line of the U* distribution (contour) This method of analysis has been verified in physical experimentation. Load path calculation using U* index In a structure, the main portion of the load is transferred through the stiffest route. The U* index represents the internal stiffness of every point within ...

Mariners' Museum And Park
The Mariners' Museum and Park is located in Newport News, Virginia, United States. Designated as America’s ''National Maritime Museum'' by Congress, it is one of the largest maritime museums in North America. The Mariners' Museum Library, contains the largest maritime history collection in the Western Hemisphere. History The museum was founded in 1930 by Archer Milton Huntington, son of Collis P. Huntington, a railroad builder who brought the Chesapeake and Ohio Railway to Warwick County, Virginia, and who founded the City of Newport News, its coal export facilities, and Newport News Shipbuilding in the late 19th century. Huntington and his wife Anna acquired of land that now holds of exhibition galleries, a research library, a lake, a five-mile shoreline trail with 14 bridges, and over 35,000 maritime artifacts from around the world. After the land acquisition took place, the first two years were devoted to creating and improving a natural park and constructing a dam ...

Isles Of Shoals
The Isles of Shoals are a group of small islands and tidal ledges situated approximately off the east coast of the United States, straddling the border of the states of Maine and New Hampshire. They have been occupied for more than 400 years, first by fishing communities and more recently as the site of private homes, a large seasonal hotel and a marine research facility. History Some of the islands were used for seasonal fishing camps by Indigenous peoples and first settled by Europeans in the early 17th century. They became one of the many fishing areas for the young British and French colonies. This was one of the most northern fishing ports, the closest one to the south being Rockport, Massachusetts. The Isles of Shoals were named the "Smith Iles" by English explorer Capt. John Smith after sighting them in 1614. This name did not last once colonization of New England by the British began. The first recorded landfall of an Englishman was that of explorer Captain Christopher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Foster (Kittery, Maine)
Fort Foster, now part of Fort Foster Park, is a historic fort active 1901-1946 on the southwest tip of Gerrish Island in the Kittery Point area of Kittery, Maine. The park includes beaches and trails. Battery Bohlen and Battery Chapin were the major parts of the fort. History The land was acquired by the U.S. federal government in 1872 and the fort was built from 1898 to 1901 as part of the large-scale Endicott Program. Other forts of this era in the Coast Defenses of Portsmouth included Fort Constitution and Fort Stark.Berhow, p. 205 The site was a sub-post of Fort Constitution and was named for American Civil War-era Brevet Major General John G. Foster of New Hampshire. Fort Foster originally had two gun batteries: Battery Bohlen with three 10-inch (254 mm) M1895 disappearing guns and Battery Chapin with two 3-inch (76 mm) M1902 guns on pedestal mounts. Battery Bohlen was built in 1898-1901 and Battery Chapin was completed in 1904. Battery Bohlen was named for Brigadier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Scull
A double scull is a rowing boat used in the sport of competitive rowing. It is designed for two persons who propel the boat by sculling with two oars each, one in each hand. Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to reduce drag to a minimum. They usually have a fin towards the rear, to help prevent roll and yaw. Originally made from wood, shells are now almost always made from a composite material (usually carbon-fibre reinforced plastic) for strength and weight advantages. The riggers in sculling apply the forces symmetrically to each side of the boat. Double sculls is one of the classes recognized by the International Rowing Federation and the Olympics. In contrast to the combination of the coxed pair, in which the distribution of the riggers means the forces are staggered alternately along the boat, the symmetrical forces in sculling make the boat more efficient and so the double scull is faster than the ...

Single Scull
A single scull (or a scull) is a rowing boat designed for a single person who propels the boat with two oars, one in each hand. Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to minimize drag. They have riggers, which apply the forces symmetrically to each side of the boat and (usually) a fin towards the rear which helps prevent roll and yaw. Originally made from wood, shells are now almost always made from a composite material (usually carbon-fibre reinforced plastic) for strength and weight advantages. Recreational single sculls tend to be shorter and a little wider than racing boats and can have a slightly flattened hull shape to provide more stability. Recreational single sculls can be made of a variety of materials including carbon fiber, fiberglass, wood or rotomoulded polyethylene. The single scull is the 2nd slowest category of racing boat (faster than the coxed pair), and competitors are recognised by other ...

Rowley, Massachusetts
Rowley is a New England town, town in Essex County, Massachusetts, Essex County, Massachusetts, United States. The population was 6,161 at the 2020 census. Part of the town comprises the census-designated place of Rowley (CDP), Massachusetts, Rowley. History The area was inhabited by the Agawam people under sachem Chief Masconomet, Masconomet. Although the area that would become Rowley was colonized by English settlers starting in 1639, it was not until 1700 that the town would pay Masoconomet's heirs nine pounds for a quitclaim deed. In spring of 1638 Rowley was originally colonized as a plantation by Reverend Ezekiel Rogers, who had arrived from England on the ship ''John of London (ship), John of London'' with approximately twenty families. The ''John of London'' also brought over the first printing press in the colonies, which was later brought to Harvard University. The following fall, on September 4, 1639, the town was incorporated, and included portions of modern-day Byfi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
