26-34" length. Can install without removing boom back end.
Starboard Adjustable Windsurfing Harness Lines
These adjustable harness lines from Starboard may be the best thought out design ever! The length adjusts across the most common range from 26"-34" with an easy to use cleat (so you can actually adjust them while you are windsurfing). The velcro boom attachment webbing wraps all the way around, so you don't have to remove your boom back end or completely disassemble the lines to install them on your boom. High density polyurethane tubing covers the no-stretch line, so they will last a long time.
If you are racing in any windsurfing class these lines are a must have and many foiling windsurfers are finding that they want easy to adjust lines as well.
