Jacob's Ladder (nautical)
The term Jacob's ladder, used on a ship, applies to two kinds of rope ladders. The term may also appear without the apostrophe, as Jacobs ladder. Types The first type of Jacob's ladder is a flexible hanging ladder. It consists of vertical ropes or chains supporting horizontal, historically round and wooden, rungs. Today, flat runged flexible ladders are also called Jacob's ladders. They are used to allow access over the side of ships, and as a result, pilot ladders are often incorrectly referred to as Jacob's ladders. A pilot ladder has specific regulations on step size, spacing and the use of spreaders. It is the use of spreaders (long treads that extend well past the vertical ropes) in a pilot ladder that distinguishes it from a Jacob's ladder. When not being used, the ladder is stowed away, usually rolled up, rather than left hanging. On late 19th-century warships, this kind of ladder would replace the normal fixed ladders on deck during battle. Fixed ladders, and railings ...

Merchant Ship
A merchant ship, merchant vessel, trading vessel, or merchantman is a watercraft that transports cargo or carries passengers for hire. This is in contrast to pleasure craft, which are used for personal recreation, and naval ships, which are used for military purposes. They come in a myriad of sizes and shapes, from inflatable dive boats in Hawaii, to 5,000-passenger casino vessels on the Mississippi River, to tugboats plying New York Harbor, to oil tankers and container ships at major ports, to passenger-carrying submarines in the Caribbean. Many merchant ships operate under a "flag of convenience" from a country other than the home of the vessel's owners, such as Liberia and Panama, which have more favorable maritime laws than other countries. The Greek merchant marine is the largest in the world. Today, the Greek fleet accounts for some 16 per cent of the world's tonnage; this makes it currently the largest single international merchant fleet in the world, albeit ...

Sailing Ship Components
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the ''water'' (sailing ship, sailboat, raft, windsurfer, or kitesurfer), on ''ice'' (iceboat) or on ''land'' ( land yacht) over a chosen course, which is often part of a larger plan of navigation. From prehistory until the second half of the 19th century, sailing craft were the primary means of maritime trade and transportation; exploration across the seas and oceans was reliant on sail for anything other than the shortest distances. Naval power in this period used sail to varying degrees depending on the current technology, culminating in the gun-armed sailing warships of the Age of Sail. Sail was slowly replaced by steam as the method of propulsion for ships over the latter part of the 19th century – seeing a gradual improvement in the technology of steam through a number of developmental steps. Steam allowed scheduled services that ran at higher average speeds than saili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob
Jacob, later known as Israel, is a Hebrew patriarch of the Abrahamic religions. He first appears in the Torah, where he is described in the Book of Genesis as a son of Isaac and Rebecca. Accordingly, alongside his older fraternal twin brother Esau, Jacob's paternal grandparents are Abraham and Sarah and his maternal grandfather is Bethuel, whose wife is not mentioned. He is said to have bought Esau's birthright and, with his mother's help, deceived his aging father to bless him instead of Esau. Then, following a severe drought in his homeland Canaan, Jacob and his descendants migrated to neighbouring Egypt through the efforts of his son Joseph, who had become a confidant of the pharaoh. After dying in Egypt at the age of 147, he is supposed to have been buried in the Cave of Machpelah in Hebron. Per the Hebrew Bible, Jacob's progeny were beget by four women: his wives (and maternal cousins) Leah and Rachel; and his concubines Bilhah and Zilpah. His sons were, in orde ...

Bible
The Bible is a collection of religious texts that are central to Christianity and Judaism, and esteemed in other Abrahamic religions such as Islam. The Bible is an anthology (a compilation of texts of a variety of forms) originally written in Hebrew, Aramaic, and Koine Greek. The texts include instructions, stories, poetry, prophecies, and other genres. The collection of materials accepted as part of the Bible by a particular religious tradition or community is called a biblical canon. Believers generally consider it to be a product of divine inspiration, but the way they understand what that means and interpret the text varies. The religious texts were compiled by different religious communities into various official collections. The earliest contained the first five books of the Bible, called the Torah in Hebrew and the Pentateuch (meaning 'five books') in Greek. The second-oldest part was a collection of narrative histories and prophecies (the Nevi'im). The third co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob's Ladder
Jacob's Ladder () is a ladder or staircase leading to Heaven that was featured in a dream the Biblical Patriarch Jacob had during his flight from his brother Esau in the Book of Genesis (chapter 28). The significance of the dream has been debated, but most interpretations agree that it identified Jacob with the obligations and inheritance of the people chosen by God, as understood in Abrahamic religions. Biblical narrative The description of Jacob's Ladder appears in Genesis 28:10–19: Judaism The classic Torah commentaries offer several interpretations of Jacob's Ladder. In '' Pirkei De-Rabbi Eliezer'' 35:6-10, the ladder signified the four exiles the Jewish people would suffer before the coming of the messiah. First, the angel representing the Neo-Babylonian Empire climbed "up" 70 rungs and then fell "down": a reference to the 70-year Babylonian exile. Then, the angel representing the exile of the Achaemenid Empire went up several steps and fell, as did the ange ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liferaft
A lifeboat or liferaft is a small, rigid or inflatable boat carried for emergency evacuation in the event of a disaster aboard a ship. Lifeboat drills are required by law on larger commercial ships. Rafts ( liferafts) are also used. In the military, a lifeboat may double as a whaleboat, dinghy, or gig. The ship's tenders of cruise ships often double as lifeboats. Recreational sailors usually carry inflatable liferafts, though a few prefer small proactive lifeboats that are harder to sink and can be sailed to safety. Inflatable lifeboats may be equipped with auto-inflation (carbon dioxide or nitrogen) canisters or mechanical pumps. A quick release and pressure release mechanism is fitted on ships so that the canister or pump automatically inflates the lifeboat, and the lifeboat breaks free of the sinking vessel. Commercial aircraft are also required to carry auto-inflating liferafts in case of an emergency water landing; offshore oil platforms also have liferafts. Ship-laun ...

Wooden Ship
Wooden ship models or wooden model ships are scale representations of ships, constructed mainly of wood. This type of model has been built for over two thousand years. Basic types of wooden ship model construction There are five basic types of construction used in building a wooden ship model hull: *Solid wood hull sawn and carved from a single block of wood. *Gluing together two thinner blocks of wood so that a block is formed with the seam vertical, so that the seam will show running down that surface of the block which is to be the deck. No advantage is gained by having the seam show along the sides of the hull. *Bread and Butter Cutting four or five thinner slabs of wood (the ''Bread'') to be glued (the ''Butter'') later into a laminated block. In this case, the slabs will be oriented so that they sit one on top of the other. *Plank on bulkhead, a technique in which a series of shaped bulkheads are placed along the keel to form a shaped stage which will be covered with plank ...

Pilot Ladder
A pilot ladder is a highly specialized form of Ladder#Flexible ladders, rope ladder, typically used on board cargo ship, cargo vessels for the purposes of embarking and disembarking maritime pilot, pilots. The design and construction of the ladders is tightly specified by international regulation under the SOLAS Convention, SOLAS regime. Pilot ladders and other boarding arrangements must be carefully prepared for each operation, with the equipment inspected and verified as safe to use before each boarding takes place. Additional requirements relate to the use of man-ropes, platforms, accommodation ladders, combination ladders and securing methods. Construction The ladders are made by threading and fixing a series of hardwood, machining, machined steps, each not more than , onto two pairs of minimum diameter abacá, manila ropes, and binding each step to the ropes at intervals. At a maximum interval of eight steps, the standard step is replaced by a ''spreader'', which is an elon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ratlines
Ratlines () are lengths of thin line tied between the shrouds of a sailing ship to form a ladder. Found on all square-rigged ships, whose crews must go aloft to stow the square sails, they also appear on larger fore-and-aft rigged vessels to aid in repairs aloft or conduct a lookout from above. Rat-boards Rat-boards are lower courses in a ratline, often made of slats of wood (batten A batten is most commonly a strip of solid material, historically wood but can also be of plastic, metal, or fiberglass. Battens are variously used in construction, sailing, and other fields. In the lighting industry, battens refer to linea ...s) for support where the distance between shrouds is greatest. In some instances holes in these slats guide and organise low-tension lines between the deck and the rig. Knotting See also * Footrope References {{Sail Types Sailing rigs and rigging ...
