I can’t tell from the picture what that is. If it was coming from the bilge (like diesel fuel), I would expect it on both sides. I suggest asking the owner directly.
As for the smile, C&C did not do a great job mating the lead keel to the fortified fiberglass keel stub (or trunk). Some owners on this list have fixed the problem on their boats. My sense is that most just tolerate it. A related issue on my boat (not sure about the 30 Mark I) is that the leading edge of the keel where it meets the hull, which is forward of where the lead is bolted on, is surprisingly “non-structural.” The weight of the keel is borne by the bolts, which should be tight to the stub/trunk. However, on my boat, and I suspect there are many, the keel is glassed to the hull forward of the strong stub/trunk area. As a result, it is non uncommon to see some cracking where the leading edge of the keel meets the hull. I spoke with a naval architect who interned at C&C in the 70’s, and he explained that this area does not support the weight of the keel, and C&C was not concerned about fortifying it. He told me not to worry about the cracking, although I constantly keep an eye on it. I noticed that my friend’s 41 has the same issue.

I tried posting this a couple days ago, but I don't know if it went through. I apologize if it did--I'm not trying to be irritating. I tried searching the archives regarding my question, but didn't find anything exactly helpful. I was looking at a Mk I C&C 30, and noticed the "C&C Smile" on both sides of the keel. From what I've read, it's not a terrible problem. Certainty not a non-starter, walkway problem. But there's also a rust stain that looks like it starts above the keel joint. Anyone have any idea what this might be? It's only on the port side, not starboard, although both sides have the smile. I haven't had a chance to look closely at the boat, just a walk-around outside without the owner. I hope to look at it closer this week, including interior and looking in the bilge, but thought I'd ask here first what people think. I've linked two pictures (port and starboard). Thanks in advance for any advice or insight, Greg Rusty port: https://photos.app.goo.gl/s7juWvBn86WozXAc9 Starboard: https://photos.app.goo.gl/pPdfCkc2mTs47ZXE9
