I cannot see a need to splice a
furling line - assuming we are dealing with a single
line furler.
I wonder if what you are speaking of is the removal of part of the core of a braided
line in order to allow enough of the
line to coil onto the
furling drum.
Here is what to do: Buy the appropriate length and size for your boat. When your
jib is tightly furled your
jib sheets should have at least three wraps around the furled
jib. This is important should storms come up while your boat is slipped. It will help keep your
jib from unfurling during a storm.
As you unfurl your
jib to go sailing, you may find that there is not enough room on the
furling drum to allow you to completely set your
jib. Here is how your alleviate that problem.
1. Furl your
jib w/3 wraps of
jib sheets
2. Remove 10 feet of the inner core of your
furling line. Here is how you do that:
a. Split the weaving on the outer wrapping enough that you can pull out the core.
b. Pull out 10 ft or so and cut it and extract the cut section. This will leave you with the 1st 10 feet of your
furling line with no inner core and thus it will take up less space on the
furling drum.
c. If you find you have not removed enough inner core, repeat the above steps.
This is NOT splicing. It is simply removing the inner core of a braided
line. I suspect that this is the procedure you are refering to.
