I am interested in the irregular hole in the sole that you show in photo #1. My bilge is accessed through a long rectangular opening in the sole, and the edges of the sole are recessed to take a rectangular teak board. So all of my keel bolts are accessible through the same rectangular opening. When I bought Belle in May, 1994 she had a C&C smile – though I did not know what that was at the time. On someone’s recommendation I opened up the crack, laid in sealant (maybe 5200?), faired over the sealant, and finished painting the bottom. When I hauled out that October, the smile was back. Belle also has rust in the bilge. My keel nuts were stainless, but there were what was left of galvanized washers under the nuts. I can’t quite determine if your keel nuts are stainless or galvanized – but the keel bolts and nuts on Belle were obviously clean stainless and still pretty shiny as I recall. Anyway, over the first winter I discovered a precursor to this list and learned about the C&C smile and proper keel bolt torque. I had some new stainless backing plates made from stainless (3/16” or ¼” thick) and before the spring launch I replaced all the rusted backing plates with stainless (one bolt at a time) and properly torqued the keel bolts. Then re-faired the smile and applied bottom paint. I re-torqued the bolts during a haul out in about 2003 or 2004 (they did not seem to have loosened any in the intervening 8 or 9 years). When Belle was last hauled a couple of years ago, there was still no evidence of a smile.

Being a 43 year old boat, obviously she is an old girl, so here is what I am dealing with: There was excessive rust (Picture 1) <http://www.boatjuggler.com/images/pic1.jpg> in the bilge. After cleaning it up I discovered that there were multiple washers, or a washer and a backing plate under the keel nuts. I said "were" because although the 1.5 inch nut with and the 3 inch washer is in great shape,whatever once was under the washer is almost totally rusted off. In some areas 1/3 or more of the washer is up in air, no contact with the bottom of the bilge. (Picture 2) <http://www.boatjuggler.com/images/pic2.jpg> and what is left, I am afraid, is ready to crumble away. The bilge was full of crumbled rusted metal pieces. Also there was a very sloppy work in the area where the bilge sump is, such that you can actually see the treads of the keel bolt under the washer. (Picture 3) <http://www.boatjuggler.com/images/pic3.jpg> . The washer is halfway in the air and not totally aligned with the keelbolt. This one is the part that concerns me the most. Also on that picture you can see parts of the mat having cured in odd shapes, in front of the bolt. Perhaps someone at one time has done reinforcing, because I see a substantial layer (almost 1/2 in) additional layer of mat about 10 inches wide laid up across the bilge on the keelbolt areas. (Picture 4) <http://www.boatjuggler.com/images/pic4.jpg> Interestingly, there is no water intrusion into the bilge, and no C&C smile. I suspect it has been this way for years. I would like to remove the keelbolts, one at a time, get rid of the rusty part, fair out the bottom of the bilge and install new washers. Unfortunately the boat is in the water for wet winter storage. My question is, should I wait until I haul out next spring to do the bottom paint to do this job, or should I do it now. I have more time over the winter than I will have next spring. Also, I see no trace of any 5200 or similar under the washers. Although I have no leaks, I will add that. My questions are:, * Is it possible that this sloppy work was done at the factory, considering that this is a 1973 model ? * Did anybody else have similar issues, if so, any words of wisdom ? :) * Could I safely do this in the water ? * Any suggestions, besides using mat and epoxy to build up the area around the exposed bolt in (Picture 3) <http://www.boatjuggler.com/images/pic3.jpg> .
