What does "Preventer" mean?

Today it means: A stay line attached to a boom or mast.

A preventer is a stay line or tackle set up to prevent movement in a boom or mast and in the case of a boom it is used to prevent an accidental gybe. The preventer is usually run from the cockpit to the bow fairlead and then back on the outside to the end of the boom. The main sheet is then pulled in hard against it setting the boom in a fixed position. Using this method allows the preventer to be released quickly in an emergency.
