How to Repair Leech Line Cleat / Tensioning Device

We’re replacing our broken cleat with a Large Plastic Clamcleat (#23202). We’re also going to replace the hook-and-loop closure on our sail. Using hook and loop as a closure system for leech line — so that the leech line can be adjusted — is very common on sails, but it does not last forever. It weakens in the sun and will need to be replaced when you notice that the hook side of the tape is losing its holding strength.

The first step is to remove your existing cleat. For this you’ll need a drill bit larger than the rivets. Drill into the rivets to break them down, then use a screwdriver or similar tool to wedge under the cleat (be careful not to damage the sailcloth) and apply pressure to pop off the cleat. The new cleat is easily installed once the old one is removed. Our video will walk you step-by-step through the entire process.

The final step is replacing the old, worn-out hook and loop with new strips. This is easily done by removing the old strips with a seam ripper and sewing new ones onto the sailcloth. Seamstick Basting Tape is handy for attaching the hook-and-loop strips to the sailcloth and keeping the assembly together prior to sewing. We recommend sewing a zigzag stitch around the perimeter of your hook-and-loop assembly. Zigzag stitches are recommended for all sail repair and sail work. The Sailrite® Ultrafeed® LSZ Walking Foot Sewing Machine is the best portable, heavy-duty zigzag/straight stitch sewing machine on the market. We recommend it to all sailors and liveaboards who do their own sail and canvas sewing.
