What righting systems are sub 80kg sailors using at present?
Also it would be interesting to know if that was the case with lighter mast because (harsh generalization) slapping over 2 kg's to mast requires more than 5 kg's of skipper weight. Let's keep in mind that righting might be ordered when there is no wind and thus skipper would violating rule 1.9.1 even though in normal windy conditions righting would succeed (I do believe in righting in all conditions because it makes boat safer).
