Rigging a preventor using the boom vang on a C22
Is anyone using their boom vang as a preventor when heading downwind? If so where and how are you attaching the end that connects to the vang hound (mast end) ? I'm leaning toward something on the fore most section of the the genoa track since I generally fly a 135 and never use that section of track.
Specifically I'm thinking about two additional cars on the track with spring blocks and setting it up like the single sheet line on the genoa and attaching the mast end of the vang to the middle of the sheet. This way when I've completed a "planned gybe" I sung up the sheet on the boom side and dont have to leave the cockpit to reattach.
Any thoughts, suggestions, or warnings would be greatly appreciated.
PS. I ask because in some very variable winds last weekend we had a radical and sudden wind shift causing a violent unexpected gybe that dang near cleaned the admiral's clock. She was not happy and I want to make sure it never happens again.
