Will, Thanks for the kind words. The research was frustrating. After a long search for a centerboard schooner of the size I wanted (+ / - 60') I settled on the C.Chase because the Smithsonian could supply plans (although in a different scale) and Chapelle has at least some comments. Turns out that is all the actual information I've been able to find, including the records of the shipyard where built. I determined there was ample info. on the type of boat so I went full ahead. The advantage is there is no way someone can challenge me on some of the small detail. Practice with TurboCad on the pungy plans. It takes a while to master that.
