USCGC Point Marone
USCGC ''Point Marone'' (WPB-82331) was an Point class cutter constructed at the Coast Guard Yard at Curtis Bay, Maryland in 1962 for use as a law enforcement and search and rescue patrol boat. Since the Coast Guard policy in 1962 was not to name cutters under in length, it was designated as ''WPB-82331'' when commissioned and acquired the name ''Point Marone'' in January 1964 when the Coast Guard started naming all cutters longer than .Scheina, p 72 Construction and design details ''Point Marone'' was built to accommodate an 8-man crew.Scheina, p 71 She was powered by two VT600 Cummins diesel main drive engines and had two five-bladed propellers. The main drive engines were later replaced by VT800 Cummins engines. Water tank capacity was and fuel tank capacity was at 95% full.Scheina, p 71 Engine exhaust was ported through the transom rather than through a conventional stack and this permitted a 360 degree view from the bridge; a feature that was very useful in search and ...

Propeller
A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Operation Market Time
Operation Market Time was the United States Navy, Republic of Vietnam Navy and Royal Australian Navy operation begun in 1965 to stop the flow of troops, war material, and supplies by sea, coast, and rivers, from North Vietnam into parts of South Vietnam during the Vietnam War. Also participating in Operation Market Time were United States Coast Guard's Coast Guard Squadron One, Squadron One and Squadron Three. The U.S. Coast Guard operated, under U.S. Navy command, heavily armed patrol boats and large cutters armed with 5-inch/38-caliber gun, 5-inch naval guns, which were used in battle and gunfire support. Radar picket escort ships, based in Guam or Pearl Harbor, provided long-term presence at sea offshore to guard against Naval trawler, trawler infiltration. Originally built for World War II convoy duty, and then modified for distant early warning ("DEW") duty in the North Atlantic, their sea keeping capability made them ideal for long-term presence offshore where they provid ...

Coast Guard Squadron One
Coast Guard Squadron One, also known in official message traffic as COGARDRON ONE or RONONE, was a combat unit formed by the United States Coast Guard in 1965 for service during the Vietnam War. Placed under the operational control of the United States Navy, it was assigned duties in Operation Market Time. Its formation marked the first time since World War II that Coast Guard personnel were used extensively in a combat environment. The squadron operated divisions in three separate areas during the period of 1965 to 1970. Twenty-six s with their crews and a squadron support staff were assigned to the U.S. Navy with the mission of interdicting the movement of arms and supplies from the South China Sea into South Vietnam by Viet Cong and North Vietnamese junk and trawler operators. The squadron also provided naval gunfire support to nearby friendly units operating along the South Vietnamese coastline and assisted the U.S. Navy during Operation Sealords. As the United States' di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Vietnam
South Vietnam, officially the Republic of Vietnam (RVN; , VNCH), was a country in Southeast Asia that existed from 1955 to 1975. It first garnered Diplomatic recognition, international recognition in 1949 as the State of Vietnam within the French Union, with its capital at Saigon, before becoming a republic in 1955, when the southern half of Vietnam was a member of the Western Bloc during part of the Cold War after the 1954 Geneva Conference, 1954 division of Vietnam. South Vietnam was bordered by North Vietnam (Democratic Republic of Vietnam) to the north, Kingdom of Laos, Laos to the northwest, Khmer Republic, Cambodia to the southwest, and Thailand across the Gulf of Thailand to the southwest. Its sovereignty was recognized by the United States and 87 other nations, though it failed to gain admission into the United Nations as a result of a Soviet Union, Soviet veto in 1957. It was succeeded by the Provisional Revolutionary Government of the Republic of South Vietnam, Rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bulkhead (partition)
A bulkhead is an upright wall within the hull (watercraft), hull of a ship, within the fuselage of an airplane, or a car. Other kinds of partition elements within a ship are deck (ship), decks and deckheads. Etymology The word ''bulki'' meant "cargo" in Old Norse. During the 15th century sailors and builders in Europe realized that walls within a vessel would prevent cargo from shifting during passage. In shipbuilding, any vertical panel was called a head. So walls installed abeam (side-to-side) in a vessel's hull were called "bulkheads". Now, the term bulkhead applies to every vertical panel aboard a ship, except for the hull itself. History Bulkheads were known to the ancient Greeks, who employed bulkheads in triremes to support the back of rams. By the Athenian trireme era (500 BC), the hull was strengthened by enclosing the bow behind the ram, forming a bulkhead compartment. Instead of using bulkheads to protect ships against rams, Greeks preferred to reinforce the hull ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mess
The mess (also called a mess deck aboard ships) is a designated area where military personnel socialize, eat and (in some cases) live. The term is also used to indicate the groups of military personnel who belong to separate messes, such as the officers' mess, the chief petty officer mess, and the enlisted mess. In some civilian societies this military usage has been extended to the eating arrangements of other disciplined services such as fire fighting and police forces. The root of ''mess'' is the Old French ''mes'', "portion of food" (cf. modern French language">French ''mets''), drawn from the Latin verb ''mittere'', meaning "to send" and "to put" (cf. modern French ''mettre''), the original sense being "a course of a meal put on the table"; cfr. also the modern Italian ''portata'' with the same meaning, past participle of ''portare'', ''to bring''. This sense of ''mess'', which appeared in English in the 13th century, was often used for cooked or liquid dishes in particula ...

Galley (kitchen)
The galley is the compartment of a ship, train, or aircraft where food is cooked and prepared. It can also refer to a land-based kitchen on a naval base, or, from a kitchen design point of view, to a straight design of the kitchen layout. Ship's cooking area A fork galley is the cooking area aboard a vessel, usually laid out in an efficient typical style with longitudinal units and overhead cabinets. This makes the best use of the usually limited space aboard ships. It also caters for the rolling and heaving nature of ships, making them more resistant to the effects of the movement of the ship. For this reason galley stoves are often gimballed, so that the liquid in pans does not spill out. They are also commonly equipped with bars, preventing the cook from falling against the hot stove. A small cooking area on deck is called a caboose or ''camboose'', originating from the , which is still in use today. In English it is a term used only for a cooking area that is abovedecks. A ...

Head (watercraft)
In sailing vessels, the head is the ship's toilet. The name derives from sailing ships in which the toilet area for the regular sailors was placed at the head or bow of the vessel. Design In sailing ships, the toilet was placed in the bow somewhat above the water line with vents or slots cut near the floor level allowing normal wave action to wash out the facility. Only the captain had a private toilet near his quarters, at the stern of the ship in the quarter gallery. The plans of 18th-century naval ships do not reveal the construction of toilet facilities when the ships were first built. The Journal of Aaron Thomas aboard HMS ''Lapwing'' in the Caribbean Sea in the 1790s records that a canvas tube was attached, presumably by the ship's sailmaker, to a superstructure beside the bowsprit near the figurehead, ending just above the normal waterline. In many modern boats, the heads look similar to seated flush toilets but use a system of valves and pumps that brings sea water ...

Scuttlebutt
Scuttlebutt in slang usage means rumor or gossip, deriving from the nautical term for the cask used to serve water (or, later, a water fountain). The term corresponds to the colloquial concept of a water cooler in an office setting, which at times becomes the focus of congregation and casual discussion. Water for immediate consumption on a sailing ship was conventionally stored in a scuttled butt: a Butt (volume), butt (cask) which had been Scuttling, scuttled by making a hole in it so the water could be withdrawn. Since sailors exchanged gossip when they gathered at the scuttlebutt for a drink of water, scuttlebutt became Navy slang for gossip or rumours. Competition ''Hoisting the scuttlebutt'' is an event that Sea Scouts participate in during regattas such as the Old Salts Regatta. In the event a 50-gallon ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
