Heavy mooring lines are often passed from larger vessels to people on a mooring by smaller, weighted heaving lines. Once a mooring line is attached to a bollard, it is pulled tight. Large ships generally tighten their mooring lines using heavy machinery called mooring winches or capstans. A sailor tosses a heaving line to pass a mooring line to ...
Bitts are paired vertical wooden or metal posts mounted either aboard a ship or on a wharf, pier, or quay. The posts are used to secure mooring lines, ropes, hawsers, or cables. [1] Bitts aboard wooden sailing ships (sometime called cable-bitts) were large vertical timbers mortised into the keel and used as the anchor cable attachment point. [2]
A mooring mast, or mooring tower, is a structure designed to allow for the docking of an airship outside of an airship hangar or similar structure. More specifically, a mooring mast is a mast or tower that contains a fitting on its top that allows for the bow of the airship to attach its mooring line to the structure. [1]
A line may get a further distinction, for example sail control lines are known as "sheets" (e.g. A jib sheet). A halyard is a line used to raise and lower a sail, typically with a shackle on its sail end. Other maritime examples of "lines" include anchor line, mooring line, fishing line, marline. Common items include clothesline and a chalk line.
The control lines (ropes) on the boom act in conjunction with the halyard and leech line to ensure that the sail is trimmed most effectively. Two primary sail control lines are attached to every boom: The outhaul runs from the clew of the sail to the free end of the boom. Hauling in on (tightening) the outhaul increases foot tension in the main ...
Adjustable fairlead (lower right) leading to winch on sailboat Fairlead (Chock style) Three mooring lines running through fairlead on a Royal New Zealand Navy ship.. A fairlead is a turning point for running rigging like rope, chain, wire or line, that guides that line such that the "lead" is "fair", and therefore low friction and low chafe. [1]
The following is a list of berth types based on cargo of the ships calling: Bulk berth Used to handle either dry or liquid bulk cargo. Vessels are loaded using either excavators, conveyor belts, and/or pipelines. Storage facilities for the bulk cargo are often alongside the berth – e.g. silos or stockpiles. Container berth
In sailing, chafing is the process of wear on a line, sail or yard caused by constant rubbing and fretting. [1] Various methods are used to prevent chafing, such as employing chaffing gear or shifting halyards to move their wear-point. [2] Chafing of lines that rest on a choke on a boat can be prevented by putting a protecting material around ...
