There is already a whole thread on the subject of reefing a little farther down in the posts on this forum. This post has the very limited focus of this one particular system that Randy is experimenting with for the Worrell 1000. It is being designed for that specific purpose, and that specific race, and at this point specifically for his own boat. I don't think it is useful to try to put it into the context of reefing in normal circumstances for everyday sailing.
