Whipstaff
A whipstaff is a steering device that was used on European sailing ships from the 14th to the 18th century. Its development preceded the invention of the more complex ship's wheel and followed the simple use of a tiller to control the steering of a ship underway. In a typical arrangement, an iron gooseneck was fitted at the fore end of the tiller. Then, a metal ring was fitted over this and secured with a pin. The ring was attached to a long, thin pole (the whipstaff proper) and this pole connected the tiller to the helmsman one or more decks above it through a pivot point, roll, or ''rowle'', described as "that round piece of wood or iron wherein the whip doth go and is made turn about that it may carry over the whip from side to side with more ease." The helmsman himself still usually did not stand on the topmost deck, but rather viewed what lay ahead of the ship through a small port or hatchway in the deck above him called a ''companion''. To move the ship to port, the forward ...

Ship's Wheel
A ship's wheel or boat's wheel is a device used aboard a ship, boat, submarine, or airship, with which a helmsman steering, steers the vessel and controls its course (navigation), course. Together with the rest of the steering mechanism, it forms part of the helm (the term ''helm'' can mean the wheel alone, or the entire mechanism by which the rudder is controlled). It is connected to a mechanical, electric Servomechanism, servo, or hydraulics, hydraulic system which alters the horizontal angle of the vessel's rudder relative to its Hull (watercraft), 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 sh ...

Tiller
A tiller or till is a lever used to steer a vehicle. The mechanism is primarily used in watercraft, where it is attached to an outboard motor, rudder post, rudder post or stock to provide leverage in the form of torque for the helmsman to turn the rudder. A tiller may also be used in vehicles outside of water, and was seen in early automobiles. On vessels, a tiller can be used by the helmsman directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel. Rapid or excessive movement of the tiller results in an increase in drag and will result in braking or slowing the boat. Description A tiller is a lever used to steer a vehicle. It provides leverage in the form of torque to turn the device that changes the direction of the vehicle, such as a rudder on a watercraft or the surface wheels on a wheeled vehicle. A tiller can be used by directly pulling or pushing it, but it may also be moved remotely using a whipstaff, tiller lines, or a sh ...

Sailing Ship
A sailing ship is a sea-going vessel that uses sails mounted on Mast (sailing), masts to harness the power of wind and propel the vessel. There is a variety of sail plans that propel sailing ships, employing Square rig, square-rigged or Fore-and-aft rig, fore-and-aft sails. Some ships carry square sails on each mast—the brig and full-rigged ship, said to be "ship-rigged" when there are three or more masts. Others carry only fore-and-aft sails on each mast, for instance some schooners. Still others employ a combination of square and fore-and-aft sails, including the barque, barquentine, and brigantine. Early sailing ships were used for river and coastal waters in Ancient Egypt and the Mediterranean. The Austronesian peoples developed maritime technologies that included the fore-and-aft crab-claw sail and with catamaran and outrigger boat, outrigger hull configurations, which enabled the Austronesian expansion into the islands of the Indo-Pacific. This expansion originated in Ta ...

Gooseneck (sailing)
The gooseneck is the swivel connection on a sailboat by which the boom attaches to the mast. The boom may pivot in any direction, from side to side or up and down, by swiveling on the gooseneck. The gooseneck may be a two-axis swivel as pictured. Having an integrated shackle for the tack Thermoproteati is a kingdom of archaea. Its synonym, "TACK", is an acronym for Thaumarchaeota (now Nitrososphaerota), Aigarchaeota, Crenarchaeota (now Thermoproteota), and Korarchaeota (now Thermoproteota), the first groups discovered. They ... is common. Goosenecks on older rigs may be formed by a loop attached to the end of the boom that fits loosely about the mast. References {{Sail Types Sailing rigs and rigging ...

Duyfken
''Duyfken'' (; ), also in the form ''Duifje'' or spelled ''Duifken'' or ''Duijfken'', was a small ship built in the Dutch Republic. She was a fast, lightly armed ship probably intended for shallow water, small valuable cargoes, bringing messages, sending provisions, or privateering. The tonnage of ''Duyfken'' has been given as 25–30 Last (unit), lasten (). In 1606, during Janszoon voyage of 1605-6, a voyage of discovery from Bantam (Banten), Java (island), Java, captained by Willem Janszoon, she encountered the Australian mainland. Janszoon is credited with the first authenticated European landing on Australia. In 1608, the ship was damaged beyond repair. A ship replica, reproduction of ''Duyfken'' was built in Australia and launched in 1999. Voyages In 1595, a ship named ''Duyfken'' sailed in the first expedition to Bantam (city), Bantam. After returning in August 1597, this ship was renamed ''Overijsel'' and also sailed in the second and fourth expedition to the East Indies ...

Sailboat Components
A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture. Types Although sailboat terminology has varied across history, many terms have specific meanings in the context of modern yachting. A great number of sailboat-types may be distinguished by size, hull configuration, keel type, purpose, number and configuration of masts, and sail plan. Popular monohull designs include: Cutter The cutter is similar to a sloop with a single mast and mainsail, but generally carries the mast further aft to allow for two foresails, a jib and staysail, to be attached to the head stay and inner forestay, respectively. Once a common racing configuration, today it gives versatility to cruising boats, especially in allowing a small staysail to be flown from the inner stay in high winds. Catboat A catboat has a single mast mounted far forward ...
