Caïque
A caïque ( el, καΐκι, ''kaiki'', from tr, kayık) is a traditional fishing boat usually found among the waters of the Ionian or Aegean Sea, and also a light skiff used on the Bosporus. It is traditionally a small wooden trading vessel, brightly painted and rigged for sail. The caïque is also a typical case of positioning the widest beam far aft, with a long sharp bow. Aegean fishing boat Construction Caïques are often built on the foreshore in a shipyard, from pine wood. The hull of the craft is built with sawn ribs and a timber keel, stem, etc. covered with carvel planking, terminated with the deck. The frame of the craft is often painted with orange primer, to preserve and seal the timber. The caïque usually has a short mast . A bowsprit is stayed by rigging. In the stern of the caïque the predominant form is the tiller. These wooden steering arms are sometimes carved in the face of a dog or animal. The caïque often has a horizontal windlass mounted over t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horizontal Plane
In astronomy, geography, and related sciences and contexts, a '' direction'' or ''plane'' passing by a given point is said to be vertical if it contains the local gravity direction at that point. Conversely, a direction or plane is said to be horizontal if it is perpendicular to the vertical direction. In general, something that is vertical can be drawn from up to down (or down to up), such as the y-axis in the Cartesian coordinate system. Historical definition The word ''horizontal'' is derived from the Latin , which derives from the Greek , meaning 'separating' or 'marking a boundary'. The word ''vertical'' is derived from the late Latin ', which is from the same root as ''vertex'', meaning 'highest point' or more literally the 'turning point' such as in a whirlpool. Girard Desargues defined the vertical to be perpendicular to the horizon in his 1636 book ''Perspective''.

Caique
Caique ( or ) refers to a group of four species of parrots in the genus ''Pionites'' endemic to the Amazon Basin in South America. Name The term "caique" is primarily used in aviculture, with ornithologists typically referring to them as the "black-headed parrot and "white-bellied parrot" (which is sometimes further split into three separate species - green-thighed parrot, yellow-tailed parrot and black-legged parrot) to describe the nominal species. They have historically been called the “seven-colored parrot”. They are relatively small and stocky, with a short, square tail and bright colors; this may be why they are referred to as “caique” based on the term for a similarly described Turkish vessel. Description The two primary nominal species are best distinguished by the black-headed caique's black crown; both have white “bellies”. Their typical weight is 150–170 grams, with the white-bellied species being the larger and heavier of the two nominal species. ...

Fiberglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1, ...

Mykonos
Mykonos (, ; el, Μύκονος ) is a Greek island, part of the Cyclades, lying between Tinos, Syros, Paros and Naxos. The island has an area of and rises to an elevation of at its highest point. There are 10,134 inhabitants according to the 2011 census, most of whom live in the largest town, Mykonos, which lies on the west coast. The town is also known as ''Chora'' (i.e. 'Town' in Greek, following the common practice in Greece when the name of the island itself is the same as the name of the principal town). Mykonos's nickname is "The Island of the Winds", due to the very strong winds that usually blow on the island. Tourism is a major industry and Mykonos is known for its vibrant nightlife and for being a gay-friendly destination with many establishments catering for the LGBT community. History Herodotus mentions Carians as the original inhabitants of the island. Ionians from Athens seem to have followed next in the early 11th century BC. There were many people living on t ...

Corfu
Corfu (, ) or Kerkyra ( el, Κέρκυρα, Kérkyra, , ; ; la, Corcyra.) is a Greek island in the Ionian Sea, of the Ionian Islands, and, including its small satellite islands, forms the margin of the northwestern frontier of Greece. The island is part of the Corfu regional unit, and is administered by three municipalities with the islands of Othonoi, Ereikoussa, and Mathraki.https://corfutvnews.gr/diaspasi-deite-tin-tropologia/ The principal city of the island (pop. 32,095) is also named Corfu. Corfu is home to the Ionian University. The island is bound up with the history of Greece from the beginnings of Greek mythology, and is marked by numerous battles and conquests. Ancient Korkyra took part in the Battle of Sybota which was a catalyst for the Peloponnesian War, and, according to Thucydides, the largest naval battle between Greek city states until that time. Thucydides also reports that Korkyra was one of the three great naval powers of fifth century BC Greece, alo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

Topsides
The topsides on a boat, ship, watercraft, or floating production storage and offloading (FPSO) vessel, is that part of the hull between the waterline and the deck.Rognaas, G., Xu, J., Lindseth, S., & Rosendahl, F. (2001). Mobile offshore base concepts. Concrete hull and steel topsides. ''Marine Structures'', ''14''(1-2), 5-23. It includes the visible parts of the bow, stern, sheer, and, if present, tumblehome. On an offshore oil platform, topsides refers to the upper half of the structure, above the sea level, outside the splash zone, on which equipment is installed. This includes the oil production plant, the accommodation block and the drilling rig A drilling rig is an integrated system that drills wells, such as oil or water wells, or holes for piling and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill wat .... They are often modular in design and so can be changed out if necessary allo ...

Prow
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ve ...
