Does anyone have a diagram and parts list (blocks, cleats, line length) for a genoa cunningham system? Steve Kiemele 3009 Cahoots

There seems to be a "harken approved" e-z setup that's in their rigging guide but all the hardware and lines are on deck--which we don't like as it's more lines under the bowman's feet. My boat came with an interesting system that may have been standard in the early 80's: the wire cunningham is led down thru the stemfitting (through a small hole, not a significant source of water intrusion) to a block attached to one of the three bolts of the stem fitting. When then use a 4:1 purchase system attached to the small foward bulkhead and have the control line run along the starboard inside of the hull and to cam cleat mounted just inside the hatch. I didn't want to drill holes in the boat for the turning block or the cam cleat, so I expoxied a small square of marine plywood to the hull and used self-tapping screws to seat the hardware--the loads aren't that bad and the system seems to work well with the added benefit of everything being down below the deck. I'll send some pictures next time I go down to the boat. -Pierson

Pierson, That setup you described is not class legal.

uh oh...could it be this one: 7. PROHIBITIONS 7.1.13 Any equipment or device to feed halyards or control lines below deck Does this mean that while the spinnaker is in it's launching bag [b]below the deck[/b] the spin halyard and sheets must be disconnected? -p

I think this one gets it more accurately: 7.1.12 Bushed or unbushed holes or slots to feed halyards or control lines through the deck, hull or transom. 7.1.13 Any equipment or device to feed halyards or control lines below deck. I believe that the spinnaker doesn't fall under any of these prohibitions, because neither its halyard or control lines pass through the deck or hull, just through the companionway.

As far as appropriate blocks goes and other assorted hardware, I set up the genoa cunningham with 2 Harken Micro Cams (H423) with appropriate fairleads on them (H424) placed beside the forward stancion bases, and then 6 H2651 Carbo Ti-Lite Blocks (The ones that have no metal and you tie to whatever you want to attach them to, or create your own beckets). On each side, tie one to the forward stanchion base. At the bow use one block on the end of a piece of line which passes through a turning block at the stem fitting, (the turning block positioned in a position so that it pulls as parallel to the luff of the sail as possible), with a hook for the sail on the other end. Thorugh this block, pass a short piece of line which attaches to the remaining two blocks, and form beckets, to which you will end the line which is going through the block at the stanchion base... so becket -> stanchion block -> becket block -> cam cleat. This gives you a 6:1 cunninham that is adjustable from both sides of the boat. Unfortunately I can't remember exactly how much line went into this, though I think the quantities are on APS or Layline's site, which worked out about right.
