Underway, or under way, is a nautical term describing the state of a vessel. "Way" arises when there is sufficient water flow past the rudder of a vessel that it can be steered. A vessel is said to be underway if it meets the following criteria: [1]
If a vessel is adrift and not being propelled by any instrument or device, it is said to be underway, not making way. [2]
"Under weigh" is a variation, coming from folk etymology, first used in 1749. "Under way" is likely from the Dutch onderweg or Middle Dutch onderwegen (lit. "under" or "among the ways"). Weigh is also a synonym for hanging or dangling, so that the process of raising an anchor, which causes it to hang at the end of the anchor-rope or chain is called “weighing [the] anchor” which leads to confusion between weigh and way, since both are pronounced identically. [3]
An anchor is a device, normally made of metal, used to secure a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ancora, which itself comes from the Greek ἄγκυρα.
Ton is the name of any one of several units of measure. It has a long history and has acquired several meanings and uses.
A yacht is a sailing or power vessel used for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a yacht, as opposed to a boat, such a pleasure vessel is likely to be at least 33 feet (10 m) in length and may have been judged to have good aesthetic qualities.
"Anchors Aweigh" is the fight song of the United States Naval Academy and unofficial march song of the United States Navy. It was composed in 1906 by Charles A. Zimmermann with lyrics by Alfred Hart Miles. When he composed "Anchors Aweigh", Zimmermann was a lieutenant and had been bandmaster of the United States Naval Academy Band since 1887. Miles was midshipman first class at the academy, in the class of 1907, and had asked Zimmermann to assist him in composing a song for that class, to be used as a football march. Another academy midshipman, Royal Lovell, later wrote what would be adopted into the song as its third verse.
USS Abatan (AW-4) was a Pasig-class distilling ship built for the United States Navy during World War II, named after the Abatan River located in the southwestern part of Bohol Island in the Philippines.
A sea anchor is a device that is streamed from a boat in heavy weather. Its purpose is to stabilize the vessel and to limit progress through the water. Rather than tethering the boat to the seabed with a conventional anchor, a sea anchor provides hydrodynamic drag, thereby acting as a brake. Normally attached to a vessel's bows, a sea anchor can prevent the vessel from turning broadside to the waves and being overwhelmed by them.
USS Lynx (AK-100) was a Crater-class cargo ship commissioned by the US Navy for service in World War II. Lynx was the third US Navy vessel to bear the name, but unlike previous ships this one was named after the constellation Lynx. She was responsible for delivering troops, goods and equipment to locations in the Asiatic-Pacific Theater.
This glossary of nautical terms is an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water. Some remain current, while many date from the 17th to 19th centuries. The word nautical derives from the Latin nauticus, from Greek nautikos, from nautēs: "sailor", from naus: "ship".
Ship stabilizers are fins or rotors mounted beneath the waterline and emerging laterally from the hull to reduce a ship's roll due to wind or waves. Active fins are controlled by a gyroscopic control system. When the gyroscope senses the ship roll, it changes the fins' angle of attack so that the forward motion of the ship exerts force to counteract the roll. Fixed fins and bilge keels do not move; they reduce roll by hydrodynamic drag exerted when the ship rolls. Stabilizers are mostly used on ocean-going ships.
The USS Albireo (AK-90) was a Crater-class cargo ship in the service of the US Navy in World War II and manned by a US Coast Guard crew. She was the only ship of the Navy to have borne this name. She is named after Albireo, a star in the constellation of Cygnus.
USS Aludra (AK-72) was a Crater-class cargo ship in the service of the US Navy in World War II. Named after the star Aludra in the constellation Canis Major, it was the first ship of the Navy to bear this name.
USS Terror (CM-5) was a fleet minelayer of the United States Navy, the only minelayer of the fleet built specifically for and retained for minelaying during World War II.
USS LST-31 was a United States Navy LST-1-class tank landing ship used exclusively in the Asiatic-Pacific Theater during World War II. Like many of her class, she was not originally named and is properly referred to by her hull designation. Later she was named for Addison County, Vermont. She was the only US Naval vessel to bear the name.
USS Broadwater (APA-139) was a Haskell-class attack transport in service with the United States Navy from 1945 to 1946. She was scrapped in 1974.
USS Amphitrite (ARL-29) was one of 39 Achelous-class landing craft repair ships built for the United States Navy during World War II. Named for Amphitrite, she was the third U.S. Naval vessel to bear the name.
Weigh anchor is a nautical term indicating the final preparation of a sea vessel for getting underway.
USS Auriga (AK-98) was an Auriga-class cargo ship, the only ship in her class, commissioned by the U.S. Navy for service in World War II, named after the constellation Auriga. She was responsible for delivering troops, goods and equipment to locations in the war zone.
USS Azimech (AK-124) was a Crater-class cargo ship commissioned by the US Navy for service in World War II, named after the Azimech, the other name of Spica, the brightest star in constellation Virgo. She was responsible for delivering troops, goods and equipment to locations in the war zone.
USS Artemis (SP-593), launched as the steam yacht Cristina then upon sale the yacht was renamed Artemis. The yacht was purchased by the United States Navy during World War I and the name was retained. Artemis was armed with guns and depth charges and sent to Europe as a patrol craft to protect Allied ships from German submarines and other dangers. The patrol yacht was renamed Arcturus in 1918. Post-war she was returned to the United States and turned over to the United States Coast and Geodetic Survey. Later, again Artemis, the vessel was in civilian operation until burning and sinking in 1927.
