Sail repair sticky tape is an on-board necessity for urgent sail repair while at sea. Be sure to keep a roll or two in your repair kit! Use Nylon repair tape for spinnaker and drifter repairs. Dacron sticky tape is primarily used for temporary repairs to working sails (main, jib, genoa). There is also a Kevlar/Mylar sticky tape for racing sailors. The use of sticky tape can be made more permanent by sewing around the patch perimeter.
