An accommodation ladder is a foldable flight of steps down a ship's side.
Accommodation ladders can be mounted parallel or perpendicular to the ship's board. If the ladder is parallel to the ship, it has to have an upper platform. Upper platforms are mostly turnable. The lower platform (or the ladder itself) hangs on a bail and can be lifted as required.
To prevent damage to boats going under the ladder as the water level rises and falls, a boat fender is fitted to the end of the ladder.
The ladder has handrails on both sides for safety. Accommodation ladders are constructed in such a way that the steps are horizontal whatever the angle of inclination of the ladder. The lower end the ladder/lower platform is based on a roll to compensate for the motion of the ship in relation to the quay.
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top, or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline.
A ladder is a vertical or inclined set of rungs or steps.
The Hiram M. Chittenden Locks, or Ballard Locks, is a complex of locks at the west end of Salmon Bay in Seattle, Washington's Lake Washington Ship Canal, between the neighborhoods of Ballard to the north and Magnolia to the south.
A deck is a permanent covering over a compartment or a hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-storey building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure. Decks for some purposes have specific names.
This is a glossary of nautical terms; an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water, but not necessarily on the sea. 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.
A dive boat is a boat that recreational divers or professional scuba divers use to reach a dive site which they could not conveniently reach by swimming from the shore. Dive boats may be propelled by wind or muscle power, but are usually powered by internal combustion engines. Some features, like convenient access from the water, are common to all dive boats, while others depend on the specific application or region where they are used. The vessel may be extensively modified to make it fit for purpose, or may be used without much adaptation if it is already usable.
An assault course is a trail that combines running and exercising. It was more popular in the 1970s than it is now. It is often used in military training. The prime use is to evaluate progress and weaknesses of the individual or the team involved. The term Assault Course is sometimes replaced by Obstacle Course, which some view as more accurate. Confidence Courses is another term used. There are also specific Urban Obstacle Courses and Night Obstacles Courses. An Obstacle Course Race (OCR) is a civilian sporting and fitness challenge event which combines obstacles and cross country running.
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 Jacob's ladder is a folk toy consisting of blocks of wood held together by strings or ribbons. When the ladder is held at one end, blocks appear to cascade down the strings. This effect is a visual illusion which is the result of one block after another flipping over. It may be considered a kinetic illusion, where the blocks appear to change position when they do not. Its name Jacob's Ladder comes from the biblical ladder to heaven, mentioned in Genesis 28:12.
The Panama Canal locks are a lock system that lifts ships up 85 feet to the main elevation of the Panama Canal and down again. The original canal had a total of six steps for a ship's passage. The total length of the lock structures, including the approach walls, is over 1.9 miles (3 km). The locks were one of the greatest engineering works ever to be undertaken when they opened in 1914. No other concrete construction of comparable size was undertaken until the Hoover Dam, in the 1930s.
A fishing vessel is a boat or ship used to catch fish in the sea, or on a lake or river. Many different kinds of vessels are used in commercial, artisanal and recreational fishing.
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. It includes the visible parts of the bow, stern, sheer, and, if present, tumblehome.
Tree stands or deer stands are open or enclosed platforms used by hunters. The platforms are secured to trees in order to elevate the hunter and give them a better vantage point. A tripod stand is a similar device, but because it is freestanding rather than attached to a tree, it is not technically a tree stand.
The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite the bow, the foremost part of a ship. Originally, the term only referred to the aft port section of the ship, but eventually came to refer to the entire back of a vessel. The stern end of a ship is indicated with a white navigation light at night.
A berth is a bed or sleeping accommodation on vehicles. Space accommodations have contributed to certain common design elements of berths.
A pilot ladder is a highly specialized form of rope ladder, typically used on board cargo vessels for the purposes of embarking and disembarking pilots. The design and construction of the ladders is tightly specified by international regulation under the SOLAS regime.
Bagan or bagang is a fishing instrument that uses nets and lights so that it can be used for light fishing, originating from Indonesia. Bagan is floated out to the sea to catch fishes, squids, and shrimps, and remain in the sea for several days or even months. The catch would be transported to land using other boats.
The Com-Pac Eclipse is an American trailerable sailboat that was designed by the Hutchins Design Team as a pocket cruiser and first built in 2004.
