A chainplate is a metal plate used to fasten a shroud or stay to the hull of a sailboat. One end of the chainplate is normally fastened to a turnbuckle which is connected to the shroud or stay, whereas the remainder of the chainplate normally has multiple holes that are bolted to the hull, or the chains. [1] This distributes the load across the hull, making it possible for a somewhat lighter hull to support the load of the shrouds and stays.
On a sailing boat, the shrouds are pieces of standing rigging which hold the mast up from side to side. There is frequently more than one shroud on each side of the boat.
Standing rigging comprises the fixed lines, wires, or rods, which support each mast or bowsprit on a sailing vessel and reinforce those spars against wind loads transferred from the sails. This term is used in contrast to running rigging, which represents the moveable elements of rigging which adjust the position and shape of the sails.
Boat building is the design and construction of boats and their systems. This includes at a minimum a hull, with propulsion, mechanical, navigation, safety and other systems as a craft requires.
The Zodiac Milpro Futura Commando 470 or in short FC470 Combat Rubber Raiding Craft (CRRC), also known as the "Combat Rubber Reconnaissance Craft," is a specially fabricated rubber inflatable boat often used by the U.S. Navy, U.S. Marine Corps, the U.S. Army, and others. The CRRC is typically called "Zodiac," referring to the boat's manufacturer, Zodiac Milpro.
This glossary of nautical terms is an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water. Some remain current, while many date from the 17th to 19th centuries. The word nautical derives from the Latin nauticus, from Greek nautikos, from nautēs: "sailor", from naus: "ship".
Stays are ropes, wires, or rods on sailing vessels that run fore-and-aft along the centerline from the masts to the hull, deck, bowsprit, or to other masts which serve to stabilize the masts.
Clinker built is a method of boat building in which the edges of hull planks overlap each other. Where necessary in larger craft, shorter planks can be joined end to end, creating a longer strake or hull plank.
The top on a traditional square rigged ship is the platform at the upper end of each (lower) mast. This is not the masthead "crow's nest" of the popular imagination – above the mainmast is the main-topmast, main-topgallant-mast and main-royal-mast, so that the top is actually about 1/4 to 1/3 of the way up the mast as a whole.
A porthole, sometimes called bull's-eye window or bull's-eye, is a generally circular window used on the hull of ships to admit light and air. Though the term is of maritime origin, it is also used to describe round windows on armored vehicles, aircraft, automobiles and even spacecraft.
The masts of traditional sailing ships were not single spars, but were constructed of separate sections or masts, each with its own rigging. The topmast is one of these.
A deadeye is an item used in the standing and running rigging of traditional sailing ships. It is a smallish round thick wooden disc with one or more holes through it, perpendicular to the plane of the disc. Single and triple-hole deadeyes are most commonly seen. The three-holed blocks were called deadeyes because the position of the three holes resemble the eye and nose sockets of a sheep's skull.
Hasholme logboat is a late Iron Age boat discovered at Hasholme, an area of civil parish of Holme-on-Spalding-Moor in the East Riding of the English county of Yorkshire. It is now on display in the Hull and East Riding Museum, in Hull.
The Dart 18 is a one-design 18-foot (5.5 m) long glassfibre sailing catamaran. It is designed to be sailed by two people and can achieve speeds of up to 20 knots. This is reflected in its Portsmouth Yardstick of 805 and D-PN of 76.3
The Topcat is a one-design sailing catamaran boat class which is divided into several boat sizes.
The Comus class was a class of Royal Navy steam corvettes, re-classified as third-class cruisers in 1888. All were built between 1878 and 1881. The class exemplifies the transitional nature of the late Victorian navy. In design, materials, armament, and propulsion the class members resemble their wooden sailing antecedents, but blended with characteristics of the all-metal mastless steam cruisers which followed.
An unstayed mast is a type of mast on a boat that is not supported by any stays. Unstayed masts are often seen with smaller sailing dinghies such as the Optimist, Topper and the Laser, but can also be used on larger vessels. Unstayed masts are found on traditional American catboats, Dutch fishing vessels ranging up to 60 feet, recent schooners in the 70 foot range and the large sailing yacht A. Freedom Yachts and Nonsuch produced a large number of yachts up to 45 feet with unstayed masts. Unstayed masts may provide better aerodynamics but require careful design both as far as the mast itself is concerned and as far as the vessel deck and keel design is concerned. Unstayed masts themselves are often somewhat heavier, which raises the vessel center of gravity. The deck and hull that support the mast need to be specially designed for the installation of an unstayed mast. Remarkably, unstayed masts do reduce hull loads since the standing rigging does not induce compressive loads into the mast and tensile loads in the hull sides in way of the chainplates.
The chains, also called the chain-whales or channels, were small platforms, built on either side of the hull of a ship, used to provide a wide purchase for the shrouds, and to assist in the practice of depth sounding.
The Starwind 223 is an American trailerable sailboat, that was designed by Cortland Steck and first built in 1984.
The C&C 57 is a Canadian sailboat. The design was built by C&C Yachts in Canada, but it is now out of production.
