Hi Darryl, Tim, anyone else interested. Darryl, short answer to your questions : "How are you all finding that the Mossie handles now with the spinnaker to its performance previously without? "
Performance wise, see attached pic, it explains it all.
"I would have thought that the spinnaker would have allowed for more stability (particularly for and aft) than without it and enable you to drive it more downwind? "
