C&C "smile"

I've received a variety of responses to my questions about fixing the infamous C&C smile, the crack/gap which can open up at the leading edge of the hull-keel joint on Marks I-IV. One school of thought suggests routing out the crack and filling with various sealants, ranging from Sikkaflex and the like to 3M 5200. At the other end of the spectrum, it's been suggested that the hull be taken down to gelcoat and the keel to bare metal and then the whole joint glassed over, faired, etc., never to move again. Some research has indicated that the latter won't be as monolothic as one would prefer without many layers of glass. Yet another mooted option involves bracing the keel, removing the nuts from the keelbolts and jacking up the hull so as to facilitate cleaning/smoothing of the joint before using sealant or glassing over the joint. Accordingly, I'm appreciate a sampling of responses from other skippers about which option they chose and, where appropriate, which sealant. Thanks in advance.

Re: C&C "smile"

I believe that smiles should be written in to the Constitution as a one-design feature so everyone can stop worrying about them. For myself, I have decided that since they are (roughly) aligned with flow, they are a non-issue as long as the bolts are not visible.

Silkaflex, a black rubbery compound that dries to tire like finish will fill the gap and can be painted over. I'll tell you at haul out how well it works. It was recommended by Nat's in Pickering as a solution since it adheres to the cleaned out gap and never hardens.
