Stern in the context of Cable layer

A carrack (Portuguese: nau; Spanish: nao; Catalan: carraca) is a three- or four-masted ocean-going sailing ship that was developed in the 14th to 15th centuries in Europe, most notably in Portugal and Spain. Evolving from the single-masted cog, the carrack was first used for European trade from the Mediterranean to the Baltic and quickly found use with the newly found wealth of the trade between Europe and Africa and then the trans-Atlantic trade with the Americas. In their most advanced forms, they were used by the Portuguese and Spaniards for trade between Europe, Africa and Asia starting in the late 15th century, before being gradually superseded in the late 16th and early 17th centuries by the galleon.

In its most developed form, the carrack was a carvel-built ocean-going ship: large enough to be stable in heavy seas, and capacious enough to carry a large cargo and the provisions needed for very long voyages. The later carracks were square-rigged on the foremast and mainmast and lateen-rigged on the mizzenmast. They had a high rounded stern with aftcastle, forecastle and bowsprit at the stem. As the predecessor of the galleon, the carrack was one of the most influential ship designs in history; while ships became more specialized in the following centuries, the basic design remained unchanged throughout this period.

Lashed-lug boats are ancient boat-building techniques of the Austronesian peoples. It is characterized by the use of raised lugs (also called "cleats") on the inner face of hull planks. These lugs have holes drilled in them so that other hull components such as ribs, thwarts or other structural components can be tied to them with natural fiber ropes (hence "lashed"). This allows a structure to be put together without any metal fastenings. The planks are further stitched together edge-to-edge by sewing or using dowels ("treenails") unto a dugout keel and the solid carved wood pieces that form the caps for the prow and stern. Characteristically, the shell of the boat is created first, prior to being lashed unto ribs. The seams between planks are also sealed with absorbent tapa bark and fiber that expands when wet or caulked with resin-based preparations.

Lashed-lug construction has been used on a wide size range of vessels, from small craft, such as logboats that have had planks added to their sides to increase their freeboard, to large plank-built ships. It is found in traditional boats of Maritime Southeast Asia, Melanesia, Madagascar, Micronesia, and Polynesia. It forms part of the maritime technology used by Austronesian peoples in their spread throughout the islands of the Indo-Pacific starting at 3000 to 1500 BCE. The oldest recovered remains of ships of lashed-lug construction is the Pontian boat of Malaysia dated to at around c.260–430 CE.

The aftercastle (or sterncastle, sometimes aftcastle) is the stern structure behind the mizzenmast and above the transom on large sailing ships, such as carracks, caravels, galleons and galleasses. It usually houses the captain's cabin and perhaps additional cabins and is crowned by the poop deck, which on men-of-war provided a heightened platform from which to fire upon other ships; it was also a place of defence in the event of boarding. More common, but much smaller, is the forecastle.

The corresponding term forecastle today is also used to describe the upper deck of a sailing ship forward of the foremast in general.

The bucentaur (/bjuːˈsɛntɔːr/ bew-SEN-tor; bucintoro in Italian and Venetian) was the ceremonial barge of the doges of Venice. It was used every year on Ascension Day (Festa della Sensa) up to 1798 to take the doge out to the Adriatic Sea to perform the "Marriage of the Sea" – a ceremony that symbolically wedded Venice to the sea.

Scholars believe there were four major barges, the first significant bucentaur having been built in 1311. The last and most magnificent of the historic bucentaurs made its maiden voyage in 1729 in the reign of Doge Alvise III Sebastiano Mocenigo. Depicted in paintings by Canaletto and Francesco Guardi, the ship was 35 m (115 ft) long and more than 8 metres (26 ft) high. A two-deck floating palace, its main salon had a seating capacity of 90. The doge's throne was in the stern, and the prow bore a figurehead representing Justice with sword and scales. The barge was propelled by 168 oarsmen, and another 40 sailors were required to man it.

Neurath's boat (or Neurath's ship) is a simile used in anti-foundational accounts of knowledge, especially in the philosophy of science. It was first formulated by Otto Neurath. It is based in part on the Ship of Theseus which, however, is standardly used to illustrate other philosophical questions, to do with problems of identity. It was popularised by Willard Van Orman Quine in Word and Object (1960).

Neurath used the simile in several occasions, first in "Problems in War Economics" (1913). In "Anti-Spengler" (1921), he wrote:

A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or afterend. Often rudders are shaped to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics.

Roll-on/roll-off (RORO or ro-ro) ships are cargo ships designed to carry wheeled cargo, such as cars, motorcycles, trucks, semi-trailer trucks, buses, trailers, and railroad cars, that are driven on and off the ship on their own wheels or using a platform vehicle, such as a self-propelled modular transporter. This is in contrast to lift-on/lift-off (LoLo) vessels, which use a crane to load and unload cargo.

RORO vessels have either built-in or shore-based ramps or ferry slips that allow the cargo to be efficiently rolled on and off the vessel when in port. While smaller ferries that operate across rivers and other short distances often have built-in ramps, the term RORO is generally reserved for large seagoing vessels. The ramps and doors may be located in the stern, bow, or sides, or any combination thereof.

An amphibious assault ship is a type of amphibious warfare ship designed for spearheading amphibious incursions of marines into enemy territories during an armed conflict, via launching either naval landings or air assaults and also by providing shipborne close air support and logistics for landed friendly forces. Such a ship is typically the capital ship of a dedicated fleet known as the amphibious ready group or expeditionary strike group.

Amphibious assault ships evolved from aircraft carriers converted for specific use as helicopter carriers, which, as a result, are often mistaken for conventional fixed-wing aircraft carriers. Like the aircraft carriers they were developed from, some amphibious assault ships also support V/STOL fixed-wing aircraft, and some latest models (e.g. China's Type 076) have catapult systems for assisted takeoff of fixed-wing light aircraft such as UCAVs and have a secondary role as drone carriers. Most modern AAS designs also carry landing craft with most including a well deck, usually at the stern, to support large LCACs (hovercraft) and LCUs, which can insert both infantry and combat vehicles directly onto land.

The bow (/baʊ/) is the forward part of the hull of a ship or boat, the point that is farthest forward when the vessel is underway in the usual direction. The aft end of the boat is the stern.

Prow may be used as a synonym for bow, or it may refer specifically to the foremost part of the bow above the waterline.

A ballonet is an inflatable bag inside the outer envelope of an airship which, when inflated, reduces the volume available for the lifting gas, making it more dense. Because air is also denser than the lifting gas, inflating the ballonet reduces the overall lift, while deflating it increases lift. In this way, the ballonet can be used to adjust the lift as required.

Ballonets may typically be used in non-rigid or semi-rigid airships, commonly with multiple ballonets located both fore and aft to maintain balance and to control the pitch of the airship.

Stern sculling is the use of a single oar over the stern of a boat to propel it with side-to-side motions that create forward lift in the water. The strict terminology of propulsion by oar is complex and contradictory, and varies by context. Stern sculling may also simply be referred to as "sculling", most commonly so in a maritime situation. In fresh water, and particularly in sport rowing, sculling is use of two oars on either side of the boat by each person, in contrast to sweep rowing, whereby each boat crew member employs a single oar, complemented by another crew member working on the opposite side with their oar.

An ensign is a maritime flag that is used for the national identification of a ship. It is the largest flag and is generally flown at the stern (rear) of the ship while in port. Depending on the ship's origin, it may sometimes be identical with a jack on the bow of the ship when in a port. Jacks are more common on warships than on merchant ships.

A transom is the aft transverse surface of the hull of some boats and ships forming its stern. Adding both strength and width to the stern, a transom may be flat or curved, and vertical, raked aft (known as an overhung or "counter" stern), or raked forward (and "reversed", also known as retroussé). In small boats and yachts, a flat termination of the stern is typically above the waterline, but large commercial vessels often exhibit vertical transoms that dip slightly beneath the water.

On smaller boats such as dinghies, transoms may be used to support a rudder, outboard motor, or other accessory. On some yachts the transom may include a hinged swim platform, and a lazarette for deck items and leisure toys.

A sternpost is the upright structural member or post at the aft end of a ship or a boat, to which are attached the transoms and the rearmost part of the stern.

The sternpost may either be completely vertical or may be tilted or "raked" slightly aft. It rests on or "fays to" the ship's keel.

In naval architecture, a taffrail is the handrail around the open deck area toward the stern of a ship or boat. The rear deck of a ship is often called the afterdeck or poop deck. Not all ships have an afterdeck or poop deck. Sometimes taffrail refers to just the curved wooden top of the stern of a sailing man-of-war or East Indiaman ship. These wooden sailing ships usually had hand-carved wooden rails, often highly decorated. Sometimes taffrail refers to the complete deck area at the stern of a vessel.

A taffrail should not be confused with a pushpit, which is a common name for the tubular protection rail running around the stern of a small yacht.

In naval architecture, a poop deck is a deck that forms the roof of a cabin built in the rear, or "aft", part of the superstructure of a ship.

The name originates from the French word for stern, poupe, from Latin puppis. Thus the poop deck is technically a stern deck, which in sailing ships was usually elevated as the roof of the stern or "after" cabin, also known as the "poop cabin" (or simply the poop). On sailing ships, the helmsman would steer the craft from the quarterdeck, immediately in front of the poop deck. At the stern, the poop deck provides an elevated position ideal for observation. While the main purpose of the poop is adding buoyancy to the aft, on a sailing ship the cabin was also used as an accommodation for the shipmaster and officers. On modern, motorized warships, the ship functions which were once carried out on the poop deck have been moved to the bridge, usually located in a superstructure.

The Raid on the Medway, during the Second Anglo-Dutch War between 12 June to 14 June 1667, was a successful attack conducted by the Dutch navy on English warships laid up in the fleet anchorages off Chatham Dockyard and Gillingham in the county of Kent. At the time, the fortress of Upnor Castle and a barrier chain called the "Gillingham Line" were supposed to protect the English ships.

The Dutch, under nominal command of Willem Joseph van Ghent and Lieutenant-Admiral Michiel de Ruyter, over several days bombarded and captured the town of Sheerness, sailed up the Thames Estuary to Gravesend, then sailed into the River Medway to Chatham and Gillingham, where they engaged fortifications with cannon fire, burned or captured three capital ships and ten more ships of the line, and captured and towed away the flagship of the English fleet, HMS Royal Charles, the stern of which is still on display at the Rijksmuseum in Amsterdam.
