A correctly made crimped join is by far the most reliable
method for permanently joining heavy lines together.
If you are using wire leader fishing knots try changing
to crimp joins as they are smaller and often stronger.
If you are using a powered longline, kontiki rig or
submarine where the mainline is dragged along the sea bed during setting and
retrieval a correctly made crimped join has many advantages over any other
knot.
The join in the fishing line should be double crimped on
each side of the join as shown in the diagram.
A protective tube, chafe protector or thimbles must be
used to protect the loops from scuffing on the seabed, or cutting in to each
other.
Always use the correct tool for the crimp, a Yo-zuri
Crimping tool or Jinkai Hand crimper tool is essential.
When joining lines of different sizes Sararak Deep Ocean Anglers use a metre of 130lb B/S dacron over the weaker line to maximise the
strength of the join. See diagram below.
