We did a loop of about 8 miles in 15 kt wind. Compared to my Gulfstream, less windage. Going upwind it tends to go through waves instead of over (low volume and little rocker). Cross wave you hardly notice them between the narrow hull and v bottom (that is to say it's no less stable than on flat water.)
Worst case fit adjustment will mean a new masik (and reskin), but I'll try shaving a bit here and there (masik, 1st rear deck beam) first. Or maybe shave a bit off my heels and modify the knees to hyperextend a little.
