      The padeyes on either side of the boom are  bolted onto the boom, not screwed.  They were installed by Chuck Poindexter of Sound Rigging, Essex CT.  Attaching the boom stowed preventer pennant lines to the boom bail would not lead as fair, and would tend to create a torquing load on the boom and gooseneck when stressed.

      I just installed this preventer system today in Bermuda. Chuck Poindexter at Sound Rigging Services (860-391-3944) sells everything (except the "fore guy") as a kit - drill bits included! We'll test it out on our trip South next week.

      I posted some photos of our preventer set-up on Cayenne.  It sounds quite similar to the ones described by others on this thread.  Attaching the preventer control line to a boom mounted preventer at the end nearest the gooseneck means the system is easy to set with boom out, and easy to change after gybing.  The bungee sewn into the middle of the boom mounted preventer line holds it in place on the boom when stowed and helps absorb the shocks of accidental gybes and unexpected backwinding.  The inner forestay also pictured is excellent for either storm jib or heavy weather jib, putting the roller furling genoa out of harm's way.
