as the leward bow comes up, it allows the rig to rake back slightly and tilt to windward making it more efficient...don't the ORMA60's have canting rigs so they can lean them to windward?
In a small cat with the forestay attached to both bows the situation you described will allow the mast to increase longitudinal rake temporarily.
However, the leeward shroud is always slack and increasing slack will do nothing to the transversal mast angle. As a consequence, it will not cant to windward.
