usual in saltwater fishing to use a leader at the end of the
main fishing line to resist abrasion from the fishing environment
(rocks, coral etc ) and from the fish themselves (jaws, sharp
gill plates, rough bills of sailfish and marlin etc ).
IGFA rules allow the use of a leader
up to 15 feet (4.57 metres ) long in line classes up to 20
lb (10 kg) and up to 30 feet (9.14 metres ) in line classes
over 20 lb (10 kg).
In some cases the target species or
other species present have sharp teeth which will quickly
cut monofilament leaders and necessitate the use of wire or
cable leaders or at least a short length of wire or cable
at the end of a mono leader.
As a rule, the more strands in a cable
the more supple and kink resistant it becomes. However the
diameter also increases significantly and it is more likely
that during a prolonged fight a fish will gradually be able
to cut through the individual strands making up the cable.
Itís a trade off. For a given
breaking strain single strand wire will have the greatest
bite resistance and the smallest diameter, but will also have
the greatest tendency towards kinking. At the opposite end
of the scale 49 strand cable will have the least bite resistance
and the largest diameter, but will have the greatest resistance
However having made the decision to
use either a monofilament or a wire or cable leader there
are further choices to be made.
