My spinnaker sheets go through a hole in the deck near the aft hatch, then down to a block near the floor, along to a block at the same height near the thwart and up to a jam cleat on the side of the deck. Mine’s a woody mk 1. There is also a fitting near the shroud for the guy (the sheet attached to the spinnaker pole) which you can hook the guy round and keep the pole down. On the mast there are D rings, one to attach the pole at the same position as the haliard D rings, and higher for the uphaul (which is elastic) as well. The downhaul is attached to a cleat. I must say I don’t race my boat competitively although the previous owner, who set this lot up, did.
