Most cats flying chutes don't have cleats unless they are doing long distance racing and they set up something on the windward side (cleat on the shroud, etc.) for temporary cleating. The single halyard/tack line is hard to explain with words, but I'll give it a shot.



The tack line starts at the end of the spin pole, comes back through one end of the back-to-back blocks, goes back to the end of the pole through a bullet block. It then comes back to the tramp where it hooks on to the tack of the spin. You should not ever have to pull this line.



The spin halyard starts at the head of the spinnaker, goes through the block on the spinnaker mast tang, down to the base of the mast, through a block on the spin pole, out through the empty end of the back-to-back block, and then back to a cleat on the tramp.



When you pull the spin halyard it also pulls in the tack line so that the tack of the spin is pulled out. Hopefully this helps.
