      One of the issues with the standard way of rigging the spinnaker sheet is that the sheet is behind you and also really easy to get under your feet and to sit on.

      If you tie two small blocks to the Ama arms where they meet the hull and feed the sheet from the rear block, through the new forward block on one side, across the cockpit and then to the new block on the other side and back to the other rear sheet this gives a number of advantages:

      1. It reduces the strain on the hands since the sheet wraps around the ratchet block further and so you can use thinner, lighter sheet rope.
      2. You’re less inclined to sit or stand on the sheet
      3. The spinnaker sheet is situated in front of you  next to the the jib sheet cleats so it makes gybing better (facing forward) and faster as all the sheet adjustments are in front.
      4. You only have to remember to pull on the sheet from next to the opposite forward block as you gybe and you can drop any excess old sheet without treading or sitting on it.


      • 2x Ronstan RF35101  Series 30 Orbit blocks or Harken T2 Soft Attach Carbo blocks
      • 1m x 4mm or 5mm Dyneema core rope to tie blocks to Ama arms.
      • 12.5m of 6 or 8mm sheet rope (The cheap polyester rope available from hardware stores is water repellent and soft in the hands although it doesn’t last long). Adjust the length to suit once you have tested your installation. You want it so that the sheets can lay on the tramp when the kite is furled.
      • (Optional) 2x Plastic rings  and 2x 1m x 4mm bungee cord for anti-tangle tensioning system


      Tie the blocks to the front ama arms where they meet the deck. They need to be tied loose enough so that when the sheet is under load the blocks are above the edge of the deck to avoid wear on the sheet.

      Optional: To avoid catching the sheet with the tiller extension, pass it through a small nylon ring tied to a length of shock cord. Tie one end of the shock cord to the ratchet block lashing under the tramp and exit through one of the rope loops at the front of the tramp with the ring attached to it.
