That approach seems to producing some convincing results. Again, you may want to remember that for most sailing winds were seldom abaft, even with stunsails extended from the yard arms. Most sailing was at an angle to the wind, on a tack, with the yards rotated depending upon tack and the leading edge of the sails depended upon the bolt ropes and sheets' tension. That will also improve the appearance of the gaff rigged mizzen mast. Just some observations for you to consider or pass by. Rich (PT-2)
