What is the proper way to rig a mainsail jibe preventer? *1 pt

Assume you do not have a boom brake.

I've always either run it forward to a block or cleat, then aft to the
cockpit or I've detached the vang at the mast step and put it on the
toerail. Clearly, you'd want to do this when the boom is inboard.

I give you and doug each a point.

What I've seen that makes the most sense is to run heavy line
the length of the boom tied at the end of the boom with a bowline,
and made off at the gooseneck with an eye-splice and a but of
small lilne to make it off when not in use. Then another line is
run forward on the side of the boat with the boom through the
bow cleat on that side and led back outside of everything to
the now freed eye splice.

What this does is make the work running a very long line much
easier. The other end goes to a halyard winch aft. So mainsheet
purchase system is used to tighten the whole thing up. It also is
much easier to remove. If you have a spike attached to the mast,
and you should, you can pop the shackle in a moment, or easy
it from farther aft.

I still prefer a boom brake, but if you don't have one this is the
next
best rig. It is easier to stow when not used, and easier to rig when
needed, than the typical "long line" preventer.
