Shoal Bay session testing the Isonic 87 with mast foot 1cm Aft of recommended setting with boom 4 cm higher. Sail felt way gruntier for this lightweight so might not have boom so high next time!! 29 HR fin had enough drive. Think the chop and boom height made the rig more of an issue to handle combined with the angle being too square in the bay. Angle wrong for any speed.
