A key thing I do to save a lot of money
is buy my halyards 10 feet too long. Then every year or two I cut off 1 foot of the shackle end, and tie the shackle on again. This moves all the wear points on the halyard
by 1 foot. It's at the wear points that the halyard
will fail, so by moving them I extend the life of the line by years and years.
