Whenever possible, line that has become wet in use
should be dried thoroughly before it is stowed.
Sometimes this is impossible, as with mooring lines,
which must be stowed before the ship clears port. If line
must be stowed wet, it should be laid up on grating in
long fakes or suspended in some way that will allow it to
dry as quickly as possible. It should never be covered
before it is dry.
Stretch and, usually, elongation occur when
natural-fiber line under tension is wetted down. The
line shrinks in diameter, adding more strain. When the
line dries, it does not recover to its original size and
shape. Thus its length is increased and its diameter and
strength are decreased. New line, which still contains a
large amount of its original waterproofing oil, does not
shrink as much as old line, from which much of the oil
has dissipated through exposure. Nevertheless,
whatever the condition, taut lines, such as boat falls,
must be slacked when it begins to rain or when spray
begins to wet them.
