What about sail chafe
I agree the stay should handle the load, but tying one end of a hammock around a roller furled jib could put a lot of stress on the sail cloth.I like the idea of the hammock but am not too sure of the chafe I would be placing on the sail. How about putting it between the davits?A cold beer, a cool breeze, a safety harness and don't roll out on the wrong side.Or put it under the boom, you get a different view with each tack or gybe.
