OK, set it up today, but DID not sail.

First pic showing the fine tune (from the wire) line (pink). Spi Downhaul (red) and the red/yellow course tune going aft:



second picture showing upwind sailing setup. Red/Yellow rope is cleated and the spanner is changed via the fine tune (see above).

Now below you can see that the Red/yellow rope is in tight and cleated; this rope then exits the cleat via an eye and then goes to a double ended block that has the Spi downhaul attached, it then is tied off on the other side of the trampoline:



Now loking at the 3rd pic, you round the windward mark and pull the red blob on the end of the rope, this uncleats the red/yellow rope and allows the rotation all the way out (but in the pic it is still on the tramp). Note that the double ended block is now down by the cleat.



You now get to the leeward mark and need to drop the kite, so you pull the downhaul (red rope) and in the process this pulls (via the double ended block) the red/yellow course tune back in. You are now back into upwind mode.




I'll be testing this in a couple of weeks time.
