Re: Just purchased 1981 CAL 39 MK2 Looking for Info
The air draft of a standard rig Cal 39 MK2 is approx 55 feet depending on load condition. The I dimension is 50' for the standard rig and an additional 4' for the tall mast.
The drawings show that the mast step is approximately 14" below the LWL, again depending on load. Never saw one with a cabin top, tabernacle mounted mast......certainly wasn't a Lapworth designed arrangement.
At one time there was an on line owners forum but it disappeared a few years ago, evidently no longer maintained by the individual who put it up.
My 1979 model, hull # 81 is homeported at the Hampton YC in Hampton, VA. Feel free to contact me if you have any questions.
