    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 you now have a 2:1 ratio on the sheet 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 similar)
    • 1m x 4mm or 5mm Dyneema core rope to tie blocks to Ama arms.
    • 14m of 6 or 8mm sheet rope (The cheap polyester rope available from hardware stores works well and is water repellent). 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.


    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.
