Man Overboard Rescue Turn
A man overboard rescue turn (or person overboard) is a shiphandling manoeuvre usually implemented immediately upon learning of a person having gone overboard into the sea. To bring a vessel closer to the person's location, implementations of the principles described are: the Anderson turn (or single turn), the quick turn (also known as the Q-turn or the figure eight turn), the Williamson turn, and the Scharnow turn. The choice of manoeuvre is dependent on several factors, including: * Location of the casualty * Whether the casualty is seen going overboard immediately or if their missing is delayed * Whether the ship is using engines or using sails * The space available for the vessel to steer * The training of the crew involved. Ideally, in any man overboard scenario, the casualty should be approached with the vessel downwind of the persons position, with the vessel moving upwind. The man overboard rescue turn is often carried out as part of regular drills on merchant ships a ...

Man Overboard
"Man overboard!" is an exclamation given aboard a vessel to indicate that a member of the crew or a passenger has fallen off of the ship into the water and is in need of immediate rescue. Whoever sees the person fall is to shout, "Man overboard!" and the call is then to be reported once by every crewman within earshot, even if they have not seen the victim fall, until everyone on deck has heard and given the same call. This ensures that all other crewmen have been alerted to the situation and notifies the officers of the need to act immediately to save the victim. Pointing continuously at the victim may aid the helmsman in approaching the victim. Causes A person may fall overboard for any number of reasons: they might have been struck by one of the ship's Boom (sailing), booms, they may have lost their footing on a slippery deck or while climbing the ship's ratlines, they may have deliberately jumped overboard in a suicide attempt, or any number of other reasons. Falling overbo ...

Teardrop Turn
A teardrop turn is a method of reversing the course of an aircraft or vessel so that it returns on its original path, travelling in the opposite direction, and passes through a specified point on the original path. Concept ;Aircraft: The teardrop turn has been described as a difficult maneuver which provides little margin for error, especially as an aviation procedure where a misjudgment can result in a stall and crash. The name comes from the overhead view of the track, which resembles an idealized teardrop. Teardrop turns are commonly used during air shows to make several passes over the runway, flying in opposite directions. Aircraft can use the teardrop turn to return to a fix while descending, a procedure called a teardrop penetration. Teardrop penetrations are typically performed under instrument flight rules. ;Watercraft: Ships and power boats generally use one of two types of teardrop turn to recover a man overboard "Man overboard!" is an exclamation given aboar ...

Nuclear Submarine
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" (typically diesel-electric) submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods, and the long interval between refuelings grants a virtually unlimited range, making the only limits on voyage times factors such as the need to restock food or other consumables. Thus nuclear propulsion solves the problem of limited mission duration that all electric ( battery or fuel cell powered) submarines face. The high cost of nuclear technology means that relatively few of the world's military powers have fielded nuclear submarines. Radiation incidents have occurred wit ...

Russo-Japanese War
The Russo-Japanese War (8 February 1904 – 5 September 1905) was fought between the Russian Empire and the Empire of Japan over rival imperial ambitions in Manchuria and the Korean Empire. The major land battles of the war were fought on the Liaodong Peninsula and near Shenyang, Mukden in Southern Manchuria, with naval battles taking place in the Yellow Sea and the Sea of Japan. Russia had pursued an expansionist policy in Siberia and the Russian Far East, Far East since the reign of Ivan the Terrible in the 16th century. At the end of the First Sino-Japanese War, the Treaty of Shimonoseki of 1895 had ceded the Liaodong Peninsula and Lüshun Port, Port Arthur to Japan before the Triple Intervention, in which Russia, Germany, and France forced Japan to relinquish its claim. Japan feared that Russia would impede its plans to establish a sphere of influence in mainland Asia, especially as Russia built the Trans-Siberian Railway, Trans-Siberian Railroad, began making inroads in K ...

Mainsail
A mainsail is a sail rigged on the main mast (sailing), mast of a sailing vessel. * On a square rigged vessel, it is the lowest and largest sail on the main mast. * On a fore-and-aft rigged vessel, it is the sail rigged aft of the main mast. The sail's foot is normally attached to a Boom (sailing), boom. (In extremely heavy weather, the mainsail may be lowered, and a much smaller trysail hoisted in its place). Historical fore-and-aft rigs used a four-sided gaff rigged mainsail, sometimes setting a gaff topsail above it. Whereas once the mainsail was typically the largest sail, today the mainsail may be smaller than the jib or genoa; G. Prout & Sons, Prout Catamaran#History, catamarans typically have a Mast-aft rig, mainmast stepped further aft than in a standard sloop, so that the mainsail is much smaller than the foresail. Bermuda rig The modern Bermuda rig uses a triangular mainsail aft of the mast, closely coordinated with a jib for sailing upwind. A large overlapping ...
