Waterproof lines

rope A rope is a group of yarns, plies, fibres, or strands that are twisted or braided together into a larger and stronger form. Ropes have tensile strength and so can be used for dragging and lifting. Rope is thicker and stronger than similarly ...
is not waterproof. When a ship anchors in relatively deep water (greater than about ), the anchor and rope that is let down becomes prohibitively difficult to raise again, even with a mechanism like a capstan. This ultimately limits the depths available with ordinary rope to within the weight bearing capacity of the rope. The rope will become so heavy with water it will break. The traditional instructions, according to the British Royal Navy in the age of sail, are: Three large strands of tightly woven rope of about in length are themselves tightly woven in a direction counter to the weave,Cable-laid rope

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 , the UK traditional definition of

Hawsers

are not cables. Hawsers are ropes of arbitrary length woven together to increase the strength of the overall line, but are not considered waterproof as the weave of the hawser goes with the weave of the ropes. This has been come to be known as "hawser laid" and "cable laid". Confusion between cables and hawsers is rampant because both cables and hawsers can be used through the
