The “C&C Smile” can be fixed just by tightening the keel bolts. Cracks through the bottom of the hull are a VERY different thing. Glassing around the keel might keep the water out of there, but there still would be cracks :(

The styrene-soluble binder that holds it all together doesn't dissolve in epoxy because there's no styrene in it, unlike polyester resin. There's probably no huge loss of strength overall, but you don't get the full benefit of another layer of glass with mat in that application.

After haul out I cleaned out seem filled with 4200 ,torque bolts to 300 ft. lbs and then covered with 2 layer matt , 2 layers cloth another matt and final layer of cloth using West System. Each layer was a bit wider starting at 1 in.and ending around 5 in..Inter protect in spring as weather is now going downhill. Will know if it works after haul out next year. Minimal cost so worth the try.

I had a small leak in my bilge two summers ago that strangely enough didn't go away by itself and got worse this past summer. The PO had told me about a hard grounding. I got it surveyed this fall after haul-out by a surveyor with lots of C&C experience. Turns out I have hidden grounding damage. I re-launched on Friday and sailed over to Bristol Marine in Port Credit on Sunday. Will be $$. At least I had a great sail yesterday...I had all Lake Ontario to myself.

A friends boat had an issue like this that was repaired in a quickie put-epoxy-on-it manner and it opened up while he was out. That trip was not fun :( His crack was above the keel, so we could get at it with the keel on. We ground it out and added layers of glass and epoxy outside and then did the same on the inside. I can't say it is perfect, but it is about 500 times stronger than the last "repair". Also you might want to make SURE that is where the water coming from. I would shop vac and towel dry the bilge and watch it very carefully. The 35 MK I and II keel structure is pretty strong and I would say cracks through the boat aren't common.

It is not normal to have cracks in the sump that are leaking water. I would not simply cover up the cracks without knowing how significant they are. Did your boat experience a 'hard grounding'?

So I thought a little biking and messing around in the bilge would be fun. The water in the bilge was a bit salty and the mild steel plates below the keel bolts were badly corroded so I replaced some of the plates with some 3/8" 316SS. I cleaned out the bilge and watched. When I removed the bolts, one at a time :-) there was no seepage around the bolts - a good sign I think. However there are some cracks in the sump area between the keel bolts and these are seeping water at about 100ml/day. I didn't go out for a sail so assume there would be more water ingress when the keel is under some stress. Is there some way to seal these cracks without dropping the keel? What is the thickness from the bottom of the bilge to the top of the keel stub? Can I just pour some epoxy in the the sump area? Thanks!!
