Unfortunately, every kink in the monofilm is also a weak point in the sail where cracks can occur sooner or later. In the worst-case scenario, you hit such a kink in a crash and the sail tears. It therefore makes sense to pull a rope through the top of the sails and tie it to a small loop to which you can attach the sail (e.g. to the car's towbar). Then all you have to do is grab the bottom of the mast and simply pull it out. This allows you to unhook the sail without kinking, even without help. This protects the monofilm and increases the service life of the sails.
