Heart or core: a loosely twisted strand or even yarns or filaments, which
run the length of larger ropes of more than three strands, to form a
central filler or heart. They can also be found in most braided lines; see
Admiralty eye splice.
Heaving line: a heaving line is a ‘messenger’, a light throwing line usually
of between 10 to 15mm (0.4 to 0.6in) diameter, and about 25m (82ft)
long, subsequently used to haul a heavier rope ashore. The end of the
heaving line must also be weighted in order to assist the throwing (see
heaving line knot and monkey’s fist). The thrower should keep his or her
end of the line secure, and not attach it to the cable until after it has been
successfully thrown; see also coiling a heaving line and throwing a heaving
line.
