People From Licking County, Ohio
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

USS Lydonia (SP-700)
USS ''Lydonia'' (SP-700) was United States Navy patrol vessel in commission from 1917 to 1919 that saw service during World War I. Prior to her U.S. Navy service, she had been William A. Lydon's private yacht, ''Lydonia II'', from 1912 to 1917. She spent most of the war based at Gibraltar, escorting and protecting Allied ships in the Mediterranean and along the Atlantic Ocean coast of Europe. After her U.S. Navy service ended, she served from 1919 to 1947 in the United States Coast and Geodetic Survey as the coastal survey ship USCGS ''Lydonia'' (CS-302). Construction ''Lydonia II'' was constructed for William A. Lydon, commodore of the Chicago Yacht Club, by Pusey and Jones in Wilmington, Delaware as Hull #348 under contract #1205 received 20 February 1911 and was more than 250 gross tons larger than the first yacht bearing the name, ''Lydonia I'', completed for Lydon just two years earlier.''Lydonia I'' was possibly confusingly Hull #338.

Flank Speed
Flank speed is an American nautical term referring to a ship's true maximum speed but it is not equivalent to the term ''full speed ahead''. Usually, flank speed is reserved for situations in which a ship finds itself in imminent danger, such as coming under attack by aircraft. Flank speed is very demanding of fuel and often unsustainable because of propulsion system limitations. The related term emergency may not be any faster than flank but it indicates that the ship should be brought up to maximum speed in the shortest possible time. Other speeds include ''one-third'', ''two-thirds'', ''standard'' and ''full''. One-third and two-thirds are the respective fractions of standard speed. Full is greater than standard but not as great as flank. In surface ship nuclear marine propulsion, the difference between full speed and flank speed is of lesser significance, because vessels can be run at or very near their true maximum speed for a long time with little regard for fuel expended, an ...

Deckhouse
A cabin or berthing is an enclosed space generally on a ship or an aircraft. A cabin which protrudes above the level of a ship's deck may be referred to as a deckhouse. Sailing ships In sailing ships, the officers and paying passengers would have an individual or shared cabin. The captain or commanding officer would occupy the "great cabin" that normally spanned the width of the stern and had large windows. On a warship, it was a privileged area, separate from the rest of the ship, for the exclusive use of the captain. In large warships, the cabin was subdivided into day and night cabins (bedrooms) by movable panels, called '' bulk-heads'', that could be removed in time of battle to leave the cabin clear for the gunners to use the stern chasers several of which were usually stationed in the cabin. On large three decker warships in the age of sail the captain's cabin was sometimes appropriated by the Admiral. The captain would be consigned to the cabin below on the mid ...

When a ship is under way, the bridge is manned by an officer of the watch aided usually by an able seaman acting as a lookout. During critical maneuvers the captain will be on the bridge, often supported by an officer of the watch, an able seaman on the wheel and sometimes a pilot, if required.

Liberty Ship
Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Though British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. Their production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types during World War I. The immensity of the effort, the number of ships built, the role of female workers in their construction, and the survival of some far longer than their original five-year design life combine to make them th ...
