We make this a clean and easy to rig and derig affair. The cord inserts through the daggerboard forward hole, slips into the gap between the spars at the tack and clips to itself. Easy. In light air this setup will help to hold the sail out going downwind. It also acts as a daggerboard retainer. We use domestically made bungee cord in black that is UV resistant. We crimp one sister clip and tie the other so you can adjust the tension as the cord ages. . Availability: Usually ships the next business day.
