Hi Chuck. For my preventers, I have 2 lines with eyes spliced in one end at forward end of boom. The other end is attached to the back of the boom. Then I have 2 lines going from cockpit forward to standup blocks on the foredeck. These can be also used for pole downhaul. When I'm not using the pole I will bring the lines back to the mast base. Here I can set the main sail grab the line off of the boom attach the preventer/downhill line using the installed snap shackle. I was in some nasty seas sailing down the coast of Oregon. I had both preventers attached to both downhaul lines. When I gybed I was able to loosen one while simultaneously tighten the other allowing for a controlled gybe. Email me off list and I can send you a picture.
