Dear Jerry, Yesterday I sailed my 1985 M15 (hull # 337) for the second time, maybe a little too much sail (170% genoa and full main) with increasing winds and gusting. Just the way I like it (Ha, Ha). I got scared a couple of times, but then found that the boat stiffened up and I started to have some fun. I'm not a design expert, but I have sailed for many years, in many boats and I must tell you that this boat that you designed and built is a wonderful boat. I am grateful to you and feel very lucky to have found this little gem. Thank you, Rick Langer Hudson River
