Ship's Wheel
A ship's wheel or boat's wheel is a device used aboard a water vessel to steer that vessel and control its course. Together with the rest of the steering mechanism, it forms part of the helm. It is connected to a mechanical, electric servo, or hydraulic system which alters the horizontal angle of the vessel's rudder relative to its hull. In some modern ships the wheel is replaced with a simple toggle that remotely controls an electro-mechanical or electro-hydraulic drive for the rudder, with a rudder position indicator presenting feedback to the helmsman. History Until the invention of the ship's wheel, the helmsman relied on a tiller—a horizontal bar fitted directly to the top of the rudder post—or a whipstaff—a vertical stick acting on the arm of the ship's tiller. Near the start of the 18th century, a large number of vessels appeared using the ship's wheel design, but historians are unclear when the approach was first used. Design A traditional ship's wheel is compo ...

Gloucester MA - Fisherman's Memorial
Gloucester ( ) is a cathedral city and the county town of Gloucestershire in the South West of England. Gloucester lies on the River Severn, between the Cotswolds to the east and the Forest of Dean to the west, east of Monmouth and east of the border with Wales. Including suburban areas, Gloucester has a population of around 132,000. It is a port, linked via the Gloucester and Sharpness Canal to the Severn Estuary. Gloucester was founded by the Romans and became an important city and ''colony'' in AD 97 under Emperor Nerva as '' Colonia Glevum Nervensis''. It was granted its first charter in 1155 by Henry II. In 1216, Henry III, aged only nine years, was crowned with a gilded iron ring in the Chapter House of Gloucester Cathedral. Gloucester's significance in the Middle Ages is underlined by the fact that it had a number of monastic establishments, including: St Peter's Abbey founded in 679 (later Gloucester Cathedral), the nearby St Oswald's Priory, Gloucester fo ...

Teak
Teak (''Tectona grandis'') is a tropical hardwood tree species in the family Lamiaceae. It is a large, deciduous tree that occurs in mixed hardwood forests. ''Tectona grandis'' has small, fragrant white flowers arranged in dense clusters (panicles) at the end of the branches. These flowers contain both types of reproductive organs ( perfect flowers). The large, papery leaves of teak trees are often hairy on the lower surface. Teak wood has a leather-like smell when it is freshly milled and is particularly valued for its durability and water resistance. The wood is used for boat building, exterior construction, veneer, furniture, carving, turnings, and other small wood projects. ''Tectona grandis'' is native to south and southeast Asia, mainly Bangladesh, India, Indonesia, Malaysia, Myanmar, Thailand and Sri Lanka, but is naturalised and cultivated in many countries in Africa and the Caribbean. Myanmar's teak forests account for nearly half of the world's naturally occurring teak. ...

Steering Engine
A steering engine is a power steering device for ships. History The first steering engine with feedback was installed on Isambard Kingdom Brunel's ''Great Eastern'' in 1866. Designed by Scottish engineer John McFarlane Gray and built by George Forrester and Company, this was a steam-powered mechanical amplifier used to drive the rudder position to match the wheel position. The size of ''Great Eastern,'' by far the largest ship of her day, made power steering a necessity. Large steam-powered warships with manual steering needed huge crews to turn the rudder rapidly. The Royal Navy once used 78 men hauling on block and tackle gear to manually turn the rudder on HMS ''Minotaur'', in a test of manual vs. steam powered steering. Steam-powered steering engines were employed on large steamships thereafter. The Mississippi River style steamboat ''Belle of Louisville'', (originally ''Idlewild'' and oldest in her class), is fitted with a steering engine. Original equipment when the boa ...

Engine Order Telegraph
An engine order telegraph or E.O.T., also referred to as a Chadburn, is a communications device used on a ship (or submarine) for the pilot on the bridge to order engineers in the engine room to power the vessel at a certain desired speed. Construction In early vessels, from the 19th century until about 1950, the device usually consisted of a round dial about in diameter with a knob at the center attached to one or more handles, and an indicator pointer on the face of the dial. There would also be a revolutions per minute indicator, worked by a hand crank. Modern EOTs on vessels which still use them use electronic light and sound signals. Operation Traditional E.O.T.s required a pilot wanting to change speed to "ring" the telegraph on the bridge, moving the handle to a different position on the dial. This would ring a bell in the engine room and move their pointer to the position on the dial selected by the bridge. The engineers hear the bell and move their handle to th ...

Officer Of The Watch
Watchkeeping or watchstanding is the assignment of sailors to specific roles on a ship to operate it continuously. These assignments, also known at sea as ''watches'', are constantly active as they are considered essential to the safe operation of the vessel and also allow the ship to respond to emergencies and other situations quickly. These watches are divided into work periods to ensure that the roles are always occupied at all times, while those members of the crew who are assigned to work during a watch are known as ''watchkeepers''. On a typical seafaring vessel, be it naval or merchant, personnel "keep a watch" in various locations and duties across the ship, such as the bridge and engine room. Typical bridge watchkeepers include a lookout and a deck officer who is responsible for the safe navigation of the ship; whereas in the engine room, an engine officer ensures that running machinery continues to operate within tolerances. Types of watches A wide variety of types of w ...

Starboard
Port and starboard are nautical terms for watercraft and aircraft, referring respectively to the left and right sides of the vessel, when aboard and facing the bow (front). Vessels with bilateral symmetry have left and right halves which are mirror images of each other. One asymmetric feature is where access to a boat, ship, or aircraft is at the side, it is usually only on the port side (hence the name). Side Port and starboard unambiguously refer to the left and right side of the vessel, not the observer. That is, the port side of the vessel always refers to the same portion of the vessel's structure, and does not depend on which way the observer is facing. The port side is the side of the vessel which is to the left of an observer aboard the vessel and , that is, facing forward towards the direction the vehicle is heading when underway, and starboard side is to the right of such an observer. This convention allows orders and information to be given unambiguously, witho ...

Sheave
A sheave () or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. The sheave spins on an axle or bearing inside the frame of the pulley. This allows the wire or rope to move freely, minimizing friction and wear on the cable. Sheaves can be used to redirect a cable or rope, lift loads, and transmit power. The words ''sheave'' and ''pulley'' are sometimes used interchangeably. Adjustable pulley A sheave can also refer to a pulley which has an adjustable operating diameter for use with a mechanical belt. This is accomplished by constructing the pulley out of several pieces. The two main "halves" of the pulley can be moved closer together or farther apart, thus altering the operational diameter. The usual construction is some sort of locking collar or set screws to secure the components, one half with a threaded central shaft and one half with a threaded center. By rotating the components, one can "screw" the parts ...
