Re: CT 47 center cockpit, tall main mast, need line drawings
You're in luck.
I own a 1987 Kaufman & Ladd -designed CT-49 (Mikado III, presently berthing on Lake Champlain, NY) and I have a copy of the CT-47's original line drawings. As far as I can tell, the CT-49 is just the CT-47 with a traditional transom, thus the 2 feet extra at the stern.
I'm presently at work in West Africa but I'll upload a scan of the drawings when I get back home in a couple of weeks.
