Pelican Hook

picture info	Pelican Hook A pelican hook is a piece of nautical rigging hardware It is composed of a hinged link held closed by a circumferential link capable of being released under load. Small examples are held closed by hand while the retaining link is displaced while larger examples are hit with a hammer or sledge hammer to release. The asymmetric appearance of the two hinged pieces is similar in appearance to a pelican's beak. It is frequently used to secure ships' anchors and life raft 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 (raft, liferafts) are also used. In t ... canisters but has many other applications.

picture info	Rigging Rigging comprises the system of ropes, cables and chains, which support a sailing ship or sail boat's masts—''standing rigging'', including shrouds and stays—and which adjust the position of the vessel's sails and spars to which they are attached—the ''running rigging'', including halyards, braces, sheets and vangs. Etymology According to the Encyclopædia Britannica Eleventh Edition "rigging" derives from Anglo-Saxon ''wrigan'' or ''wringing'', "to clothe". The same source points out that "rigging" a sailing vessel refers to putting all the components in place to allow it to function, including the masts, spars, sails and the rigging. Types of rigging Rigging is divided into two classes, ''standing'', which supports the mast (and bowsprit), and ''running'', which controls the orientation of the sails and their degree of reefing. Configurations differ for each type of rigging, between ''fore-and-aft rigged'' vessels and ''square-rigged'' vessels. Standing Standin ...

picture info	Sledge Hammer A sledgehammer is a tool with a large, flat, often metal head, attached to a long handle. The long handle combined with a heavy head allows the sledgehammer to gather momentum during a swing and apply a large force compared to hammers designed to drive nails. Along with the mallet, it shares the ability to distribute force over a wide area. This is in contrast to other types of hammers, which concentrate force in a relatively small area. Etymology The word sledgehammer is derived from the Anglo Saxon "''slægan''", which, in its first sense, means "to strike violently". The English words "slag", "slay", and "slog" are cognates. Uses The handle can range from to a full long, depending on the mass of the head. The head mass is usually . Modern heavy duty sledgehammers come with heads. Sledgehammers usually require two hands and a swinging motion involving the entire torso, in contrast to smaller hammers used for driving in nails. The combination of a long swinging range, ...

picture info	Pelican Pelicans (genus ''Pelecanus'') are a genus of large water birds that make up the family Pelecanidae. They are characterized by a long beak and a large throat pouch used for catching prey and draining water from the scooped-up contents before swallowing. They have predominantly pale plumage, except for the brown and Peruvian pelicans. The bills, pouches, and bare facial skin of all pelicans become brightly coloured before the breeding season. The eight living pelican species have a patchy global distribution, ranging latitudinally from the tropics to the temperate zone, though they are absent from interior South America and from polar regions and the open ocean. Long thought to be related to frigatebirds, cormorants, tropicbirds, and gannets and boobies, pelicans instead are now known to be most closely related to the shoebill and hamerkop, and are placed in the order Pelecaniformes. Ibises, spoonbills, herons, and bitterns have been classified in the same order. Fossil ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Life Raft 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 (raft, liferafts) are also used. In the military, a lifeboat may double as a whaleboat, dinghy, or Captain's gig, 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 life ...
