Line or set of lines made of rope, webbing, or cable and used in helicopter external load operations; usually placed between a swivel or the cargo hook and the load.
device used by sailors in past centuries to determine depth; a rope fixed with a lead weight was lowered overboard and then measured in fathoms (1 fathom=6 feet, or the distance of a man's armspan). Sometimes tar or wax was smeared on the end of the lead weight in order to obtain a sediment sample.
(nautical) plumb line for determining depth
A line marked at regular intervals of length, with a lead weight at the end, dropped into the sea to measure the depth. Lodestone A piece of magnetic rock carried on ships until the 18th century to re-magnetize the compass needle.
A weighted line, knotted at fathoms, lowered from the deck and used to determine water depth
Line weighted with lead for making depth soundings in water.
Sinking line used in fishing for lower line holding down nets or traps. May have a lead filament or core that would make the rope sink; also called bottom line.
a line marked off in fathoms and weighted at one end with a lead, used for measuring water depths-also called a sounding line.
That part of a rope tackle leading from the first, or fast, sheave to the drum.
A line used for sounding the depth of water under a vessel.
A line with a weight on the end used to measure depth. The lead is dropped into the water and marks on the line are read to determine the current water depth. The lead usually has a cavity to return a sample of the bottom type (mud, sand, etc.)
Support line, running from the arbor, through head and loft blocks to one of several locations on rigging batten.
