Gaff rig [1] is a sailing rig (configuration of sails, mast and stays) in which the sail is four-cornered, fore-and-aft rigged, controlled at its peak and, usually, its entire head by a spar (pole) called the gaff. Because of the size and shape of the sail, a gaff rig will have running backstays rather than permanent backstays.
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]
Swing moorings also known as simple or single-point moorings, are the simplest and most common kind of mooring. A swing mooring consists of a single anchor at the bottom of a waterway with a rode (a rope, cable, or chain) running to a float on the surface. The float allows a vessel to find the rode and connect to the anchor.
Also called bolster plate. anchor buoy A small buoy secured to a line attached to the crown of an anchor. The line allows the anchor to be unhooked from an obstruction, such as a rock or another vessel's anchor cable, so preventing raising the anchor in the normal way. [13] anchor chain . Also anchor cable. A chain connecting a ship to an anchor.
A fore-and-aft topsail may be carried above the upper or only spanker, and is called the gaff sail. To stop a full-rigged ship, except when running directly down wind, the sails of the foremast are oriented in the direction perpendicular to those of the mainmast. Thus, the masts cancel out of their push on the ship. [5]
The length of chain running diagonally up and right from the bottom-left of this picture to the upper of the two yards is the fore-lower-topsail sheet. Some of the lines on Prince William's larger sails are made of chain to handle the heavy loads while remaining flexible enough to pass through the various blocks on their route to the deck.
Winding mechanism on the Sackville Ferry in New South Wales, Australia. Cable ferries can be typified by their size and construction, their usage (passenger, animal, vehicle) and requirements (length of crossing, amount of other shipping), their cables (wire rope, chain, or both), and their propulsion (water current, engine, manual).
Also anchor rode. The anchor line, rope, or cable connecting the anchor chain to the vessel. rogue wave Any unusually large wave for a given sea state; formally, a wave whose height is more than twice the significant wave height of that sea state (i.e. the mean of the largest third of waves in a wave record). roll 1.
