Dave, Regarding the Down-haul Blocks at 75-3/4" on the Deck Layout, I had made the backing plate and mounting holes for the old design and then Bram changed them to two RF20174 Pivot Lead Blocks, mounted on the aft end of the mast step channel. I may use the old eye-strap and two RF20100's as the control blocks for the newly designed forestay adjustment system and install the new v-cleats/wedges on the wings, just aft of the righting system thru-hole. For the new down-haul design, the pivot blocks are bolted to a hybrid/glass mounting bracket that is bolted thru the mast step channel. There is space underneath for the cunningham control line to pass forward to the RF662 block. The mounting bracket raises the control lines above the spin sock. I made it by laying hybrid over a 1"x4" wooden mandrel to make a U-shaped channel long enough to fabricate two brackets, with the same hybrid/glass layup used to make the mainsheet bracket on the boom. The U-shaped channel was then half-filled with 406 filler and glass-fiber strands to make a solid block for mounting the swivel blocks. The bracket stand was cut down to 2" high, sealed with epoxy/graphite and drilled thru for the swivel block mounting holes. Below is a shot of the completed installation and the untrimmed spare bracket (standing on the sock). Bill Scheumann USA020 and USA040
