Thank you for the input Dwight, Josh, Doug, Alan, Gary and Parsons.
To collate everything Ive heard - and as long as this isnt the dreaded mast-step compression issue in the keel stub (touching wooden head as I say this) I should: Ensure the bolts are properly torqued; if they are good, leave it alone and monitor the smile at the end of this season to see if theres any progression. However, if the bolts take some torquing to get them back to spec, then I should consider grinding out the crack and making the repairs. Correct? Regarding the spot at the top of the keel stub nearer the hull, I think Ill have to grind that out and re-glass it. On the exterior, its a welt about the size of a dime, but to apply the 12:1 rule of proper patching, I would be grinding a 4 divot, layering in the glass and epoxy, and fairing. Does that sound reasonable? Doug (dallary), when you did the core sampling to test the integrity of the high density fill used in the cavity under the mast-step, how did you plug the ¼ hole you drilled? The PO did this each year on the rudder drilled a ¼ hole in the bottom to drain any water and he plugged it with caulking each spring. BTW, I got about 6 oz of water out of the rudder when I did this at haul-out (PO says that was normal). Thanks again, everyone, for your wisdom!

These materials cushion any flex between the keel and the hull. Anything applied over the bedding will likely be less squishy and more brittle (fairing compound, epoxy, barrier coat, bottom paint). I agree, it doesn't look bad. As long as water isn't leaking in or out then I wouldn't worry. Take some pictures and monitor it each time the boat is hauled out. When it is decidedly time to take action my first step would be to torque the keel bolts. If that doesn't yield improvement then attempt a repair according to the link below. https://drive.google.com/file/d/0B8pEh5lnvP1yV1JEN3YxQk1RbHc/view?usp=docsli st_api Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Mar 19, 2016 2:08 PM, "Ainslie via CnC-List" <cnc-list@cnc-list.com <javascript:_e(%7B%7D,'cvml','cnc-list@cnc-list.com');> > wrote: My keel joint seems to be opening up; there wasn't much sign of it at haul out, but now it's noticeable. Also, you can see something oozing from the crack. Whatever it is has an oily texture so I'm guessing its coming from the bilge. In the first photo, the vertical stain is the same oily ooze coming from a welt higher up on the keel stub. I think I have to address it because if something can get out, then surely water can get in. Three options: a)rout out the crack and fill with epoxy; b) fill it with 5200 (on the premise that the keel wants to flex laterally, so fill it with something flexible); or c)see how it progresses this season and see if I have an autumn project? I dont think (c) is the best option. Ive done this kind of work before Id appreciate hearing what the Listers say http://jainslieblog.blogspot.ca/ Could this have been caused by the way it's sitting in the cradle? FYI, this keel is a modified bulb, done by MarsKeel about 9 years ago. Thanks for any input.
