Probably a simple case of the "C&C smile". This has been discussed ad nauseum on this list. Many of us on this list have experienced it and repaired it.
In its most frequent occurrence, properly torquing the keel bolts and epoxying a couple layers of glass tape over it will fix it. Here's some pics of the smile on my 35-1: http://www.cncphotoalbum.com/doityourself/smile/index.htm That smile was fixed by torquing the keel bolts, digging out some crumbly stuff at the hull/keel interface, filling the dug out areas with epoxy glass, layering 4 inch biaxial tape over the hull/keel joint, fairing and painting. 20 years and 14,000 nautical miles of sailing in all conditions later, it has not recurred. Many of us on the list have similar experience with the smile. Very infrequently, more action is required. This involves dropping the keel and resealing the joint. There may be a void or two or a structural weakness around one or more of the keel bolts. Again, this has only been observed infrequently. There are folks on this list that have experience with that. Again, the most common occurrence is fixed by properly torquing the bolts. Here's a link to the torque specs posted on the C&C site: http://www.cncphotoalbum.com/doityourself/torquebolts/torquebolts.htm It was hard to tell in your pics, what is under the keel bolt nuts? Another critical piece of fixing the smile is stainless washers or plates under the nuts. Many early C&C's had steel plates which degraded allowing the keel bolts to become loose. Dennis C.
