Keith: Are you using the ratchet blocks in your setup? I'm thinking about the pole launching system. A few of our guys actually made their own by buying an aluminum pole locally, buying the bag (from Rick) and making their own snuffer ring. I think I can have a spinnaker made for about $725.

I used Harken Ratchamatics mounted on the rear crossbeam, with the sheets run forward to turning blocks on the front beam, crew trimmed from the front blocks. I had wanted to move mine forward, but did want go all the way to the shroud. The best advice is to rig the boat up and play around to see where the sheeting angle is best.
I rigged a single line halyard/tack set up, worked very nice. I supported the pole at the forestay using a small Harken swivel attached to the bottom of the forstay adjuster plate (it extended below the furler just enough). Drilled small holes in the bow lips for running the pole bridles, and ran some bridles from the bow tangs to pole at the forestay area just to limit side to side movement. For the blocks on the pole I used Harken Tie Lites to avoid putting loads on eyes and rivets. I used eye straps just to locate the lashings for the blocks. A mid pole snuffer could have easily been added to that rig. I sold the boat awhile ago, but I have a ton of pics from the process of putting the rig together.
