In the old smoking days we tied a plastic weatherproof bottle to hold the cigs and lighter to the 16's vang hook on the boom. We could have a smoke downwind in 20 knots.
We tried a a black bungee as a vang on the 16 for an ultralight wind day on a little lake somewhere in Michigan in the 80's. I was driving and I told Tim that it was time to gibe. We jibed but the vang did not get released. The boat jibed but the boom didn't. That was the end of that.
Mary and Rick were probably there on their 18 and Carl Roberts was singlehanding his to another win.
Great Times!
