Just make some out of the size you like dyneema rope, 3-4mm Bungy and plastic hook from your local marine shop. You'll put one on each wing for the cost of one harness line and this one is easy to fit and adjust. Easy to make, easy to use.No flapping about


I just embedded the bungee inside of the harness line. No flapping. Stays out of the way and the setup is clean with no extraneous lines messing about. Maybe I have PTSD from sailing I-14s but I'm always thinking about how can I keep things simple.
I like your original solution... Just wondering what size and type of cord and diameter bungee you used on the version you made with the bungee inside? Does it pull up enough computer to the version you pictured above? Thanks
