Load line mark and additional load lines on the hull of a ship. Load lines are indicated by special markings on the hull. The marking for the main load line, the summer load line, is called load line mark or Plimsoll mark (positioned amidships), the marks for other conditions are named after the condition suffixed with "load line" (e.g. winter ...
International Convention on Load Lines has 8 amendments, the last one (to make the use of the III Code mandatory) is adopted on 4 December 2013 and entered into force on 28 February 2018. [ 5 ] The Protocol of 1988 relating to the LL 1966 (LL PROT 1988) has 10 amendments, the last one is from 2018, but this amendment is related only to the ...
The total load on a particular section of a ship's hull is the sum total of all primary, secondary, and tertiary loads imposed on it from all factors. The typical test case for quick calculations is the middle of a hull bottom plate section between stiffeners, close to or at the midsection of the ship, somewhere midways between the keel and the ...
A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy), 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.
The word stevedore (/ ˈ s t iː v ɪ ˌ d ɔːr /) originated in Portugal or Spain, and entered the English language through its use by sailors. [3] It started as a phonetic spelling of estivador or estibador (), meaning a man who loads ships and stows cargo, which was the original meaning of stevedore (though there is a secondary meaning of "a man who stuffs" in Spanish); compare Latin ...
On a keelboat, "outrigger" refers to a variety of structures by which the running rigging (such as a sheet) may be attached outboard (outside the lateral limits) of the boat's hull. The Racing Rules of Sailing generally prohibit [ 3 ] such outriggers, though they are explicitly permitted on specific classes, such as the IMOCA Open 60 [ 4 ] used ...
The load line (also known as Plimsoll line) is the waterline which indicates the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy. [2] For vessels with displacement hulls, the hull speed is defined by, among other things, the waterline length.
The combination of symbol and hull number identify a modern Navy ship uniquely. A heavily modified or repurposed ship may receive a new symbol, and either retain the hull number or receive a new one. Also, the system of symbols has changed a number of times since it was introduced in 1907, so ships' symbols sometimes change without anything ...
