Mast or MAST may refer to:

Mast (sailing)

The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sail, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed masts.

Until the mid-19th century all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a conifer tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than could be made from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts), known in order of rising height above the decks as the lower, top, topgallant and royal masts. Giving the lower sections sufficient thickness necessitated building them up from separate pieces of wood. Such a section was known as a made mast, as opposed to sections formed from single pieces of timber, which were known as pole masts.

Mast (naval)

In naval tradition, a mast is a non-judicial punishment ("NJP") disciplinary hearing under which a commanding officer studies and disposes of cases involving those in his command.

If the officer conducting the proceeding is either a captain, or a lower ranking officer (typically a commander or lieutenant commander) serving as commanding officer of a naval or coast guard vessel, an aviation squadron, or similar command afloat or ashore, then the proceeding is referred to as a captain's mast.

If an admiral is overseeing the mast, then the procedure is referred to as an admiral's mast or a flag mast.

A captain's mast or admiral's mast is a procedure whereby the commanding officer must:

  • Make inquiry into the facts surrounding minor offenses allegedly committed by a member of the command;
  • Afford the accused a hearing as to such offenses; and
  • Dispose of such charges by dismissing the charges, imposing punishment under the provisions of military law or referring the case to a court-martial.

A captain's mast is not:

  • A trial, as the term "non-judicial" implies;
  • A conviction, even if punishment is imposed;
  • An acquittal, even if punishment is not imposed.

In the United States Navy and United States Coast Guard, these proceedings take place under the authority of Article 15 of the Uniform Code of Military Justice ( UCMJ).

The term mast may also refer to when a captain or commanding officer makes themself available to hear concerns, complaints or requests from their crew. Traditionally, on a naval vessel, the captain would stand at the main mast of that vessel when holding mast. The crew, who by custom did not speak with the captain, could speak to him directly at these times. It could also refer to the naval punishment of tying one to a mast and lashing them with a whip.

In modern times, a meritorious mast refers to the commanding officer taking this time to single out a member of the crew for praise and present written recognition of work well done.

Mast (Sufism)

In Sufi philosophy, a mast (pronounced "must") is a person who is overwhelmed with love for God, accompanied with external disorientation resembling intoxication. The word is coined by Meher Baba and originates from the Sufi term mast-Allah meaning "intoxicated with God" from Persian mast, lit. "intoxicated." Another interpretation of its origin is that it is derived from masti, a Persian word meaning "overpowered."

Mast (film)

Mast (botany)

Mast is the "fruit of forest trees like acorns and other nuts". It is also defined as "the fruit of trees such as beech, and other forms of Fagaceae". Alternatively, it can also refer to "a heap of nuts". The term "mast" comes from the old English word "mæst", meaning the nuts of forest trees that have accumulated on the ground, especially those used as food for fattening domestic pigs.

More generally, mast is considered the edible vegetative or reproductive part produced by woody species of plants, i.e. trees and shrubs, that wildlife species and some domestic animals consume. It comes in two forms.
