Steering oarThe steering oar or steering board is an over-sized oar or board, to control the direction of a ship or other watercraft prior to the invention of the rudder. It is normally attached to the starboard side in larger vessels, though in smaller ones it is rarely, if ever, attached. The steering oar was crucial in the invention of larger vessels in a time when the technology for rudders did not exist. Steering oars were the typical steering mechanism on larger Viking ships.
Dutch languageDutch (Endonym: Nederlands [ˈneːdərlɑnts] , Nederlandse taal) is a West Germanic language of the Indo-European language family, spoken by about 25 million people as a first language and 5 million as a second language and is the third most spoken Germanic language. In Europe, Dutch is the native language of most of the population of the Netherlands and Flanders (which includes 60% of the population of Belgium).German languageGerman (Deutsch, pronounced [dɔɪ̯tʃ] ) is a West Germanic language in the Indo-European language family, mainly spoken in Western and Central Europe. It is the majority and official (or co-official) language in Germany, Austria, Switzerland, and Liechtenstein. It is also an official language of Luxembourg, Belgium and the Italian autonomous province of South Tyrol, French autonomous region of Alsace and as well as a recognised national language in Namibia.
RudderA 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.

AircraftAn aircraft or aerial vehicle is a vehicle that can fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, drones, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons.Bow (watercraft)The bow () 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. FunctionA ship's bow should be designed to enable the hull to pass efficiently through the water.
WatercraftA watercraft or waterborne vessel is any vehicle designed for travel across or through water bodies, such as a boat, ship, hovercraft, submersible or submarine. TypesHistorically, watercraft have been divided into two main categories. Rafts, which gain their buoyancy from the fastening together of components that are each buoyant in their own right. Generally, a raft is a "flow through" structure, whose users would have difficulty keeping dry as it passes through waves.
Mirror imageA mirror image (in a plane mirror) is a reflected duplication of an object that appears almost identical, but is reversed in the direction perpendicular to the mirror surface. As an optical effect, it results from specular reflection off from surfaces of lustrous materials, especially a mirror or water. It is also a concept in geometry and can be used as a conceptualization process for 3D structures.
SpacecraftA spacecraft is a vehicle that is designed to fly and operate in outer space. Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket).
Symmetry (geometry)In geometry, an object has symmetry if there is an operation or transformation (such as translation, scaling, rotation or reflection) that maps the figure/object onto itself (i.e., the object has an invariance under the transform). Thus, a symmetry can be thought of as an immunity to change. For instance, a circle rotated about its center will have the same shape and size as the original circle, as all points before and after the transform would be indistinguishable.
Old EnglishOld English (Englisc or Ænglisc, pronounced or ), or Anglo-Saxon, is the earliest attested form of the English language, spoken in England and southern and eastern Scotland in the Early Middle Ages. It developed from the languages brought to Great Britain by Anglo-Saxon settlers in the mid-5th century, and the first Old English literature dates from the mid-7th century.
