AIR FLOW TELS RED / GREEN
Air-flow Tels are wind-on-the-sail indicators that show the air flow across the sails, allowing you to trim sails for maximum performance. The result is better boat speed, less pinching, and no guesswork about placing the jib sheet lead forward or aft. No holes are required in the sails; waterproof adhesive locator discs attach the Tels. Tels are made of ripstop nylon for maximum sensitivity and long life. The set of 14 high visibility Tels includes red and green (port and starboard colours).
