the marion bermuda race requires a boom brake or preventer.
in the ocean you will find it is easy to jibe the main even when not running.
the vang tied to the stanchion bases is an accident waiting to happen.
they suggest a
line run on either side of the boom from pad eyes on the end of the boom to
cleats on either side of the boom at the gooseneck.
then a
line is run from the cockpit to the bow with a block at the bow. this
line is then run back to either
line on the boom connected with a snap
shackle.
the
lines along the boom enable you to hook up the preventer even if the boom end is outboard. we always hook up the preventer offshore unless we are beating.
