When sailing downwind in offshore conditions (racing to Hawaii) we would rig a line (preventer) from the near the bow to the aft end of the boom. The line would be long enough to allow the boom to swing in towards the center line without passing center.
This was done to allow the boat to roll deep to leeward and not break the boom as it hit a wave. In older IOR designs including the C&C 39 we would often fly a blooper to balance the spinnaker and allow deep downwind angles. Occasionally the watches would compete on who could alternate dipping the boom and pole tip the most times in a row. In the 1982 Vic-Maui one boat broke its boom by using a hard preventer at the same time as using the boom's hitting the water as an aid to course correction. The boom and pole dipping contest did make it difficult for the off watch to eat spaghetti.

Accidental jibes can get scary So far I only ran down wind on very light wind days and for short distances.. As per my prior comment I'm a believer in beam / broad reach / gybing instead of running.. So my danger was minimized. But, I'm glad you guys made the comment, It reminded me of my boom brake I picked-up for 30 bucks at the marina swap meet last year. I believe it's a Walder. I think they are pretty good. Now that I'm getting into racing I need to rig it / test it and see if it's worth the extra clutter / hassle instead of controlling the jibe with the main sheet. http://www.boom-brake-walder.com/ Have you guys used one of those before? -Francois Rivard 1990 34+ "Take Five" Lake Lanier, Georgia
