Years ago we met a South African couple that had invented "doubly Pegs" the new revolution is cloth pegs for sail boats. They were planning to cruise from SA and sell these to the other cruisers and have a great cruising kitty. The next best idea is "they pushed onto the life lines from either side". We flew home form SA with a bunch to test for them. In the anchorage wind they ALL just blew off. At that time it was just the wooden pegs that would rust in the middle and the rust would get onto your clothes.
