It can be made of rope, chain or a combination of rope and chain. The ratio of the length of rode to the water depth is known as the scope. Holding ground is the area of sea floor that holds an anchor, and thus the attached ship or boat. [4] Different types of anchor are designed to hold in different types of holding ground. [5]
The anchor chains are pre-tensioned to ensure that the buoy is held in position above the PLEM. As the load from the tanker is applied, the heavy chains on the far side straighten and lift off the seabed to apply the balancing load. Under full design load there is still some 27 metres (89 ft) of chain lying on the bottom.
A length of chain was usually fixed at waist height to the stanchions above the chains, as an added safety measure. [2] The chains were common on large sailing vessels, but the role of leadsman and swinging the lead to obtain depth soundings declined with developments in echo sounding, and ships are rarely now equipped with chains.

The heavy weight (anchor) should be a dense material. Old rail wagon wheels are used in some places (e.g. Clontarf, Dublin, Ireland) for this purpose. In some harbours (e.g. Dun Laoghaire, Ireland), very heavy chain (e.g. old ship anchor chain) may be placed in a grid pattern on the sea bed to ensure orderly positioning of moorings.
A windlass is a machine used on ships that is used to let-out and heave-up equipment such as a ship's anchor or a fishing trawl. On some ships, it may be located in a specific room called the windlass room. An anchor windlass is a machine that restrains and manipulates the anchor chain on a boat, allowing the anchor to be raised and lowered by ...
The three ropes are so tightly wound counter to the weave of the constituent ropes that the fibers are compressed and the individual weaves stressed, sealing out the water and resulting in a length of about 180 metres (100 fathoms), the UK traditional definition of cable length. Using a cable, the raising of the anchor, or any activity ...
Cube – The cargo carrying capacity of a ship, measured in cubic metres or feet. There are two common types: Bale Cube (or Bale Capacity) – The space available for cargo measured in cubic metres or feet to the inside of the cargo battens, on the frames, and to the underside of the beams. It is a measurement of capacity for cargo in bales or ...
The Triple E class is a family of very large container ships with a capacity of more than 18,000 TEUs, which are owned and operated by Maersk Line.. With a length of 399.2 m (1,309 ft 9 in), when they were built they were the largest container ships in the world, but were subsequently surpassed by larger ones such as CSCL Globe.
