Cal 39-4 Ray Hunt design

Hi All I'm looking at buying a Cal 39 here in Annapolis and kitting it out for some cruising. I've read loads of good things about the Lapworth Cals, ie very good sailing performance, seaworthy, good comfort and self righting ratios, quality construction, solid glass hull (not cored) and so forth. I'm wondering if anyone can point me to the same kind of details on the Cal 39-4 Ray Hunt design of 1988/89? I've searched the forums and googled all to no avail! Thanks in advance. J-P Quigley
