Hi, the heavy rain here in S. Cal. delayed things here a bit. The keel bolt repair is going on as we speak. Here is what is being done.

The old rusty bolts and nuts were soaked in oxalycic acid (spelling?). He told me it changes the rusty metal from iron oxide to iron sulfide. This converts it to something that can be sealed. Then the bolt is ground down and permanently sealed in a mixture of epoxy and tar. This work has been completed.

New bolt holes are bored. 5 3/4 inch 316 stainless bolts will be put into the cast iron keel to a depth of 5 inches. Each bolt will be covered with a epoxy thread sealant prior to screwing it in. Any galvinic corrosion that does occur can be tolerated for the next 20 years. The stainless bolts are left uncoated in the bilge. The first bolt will be in by tomorrow.

The entire job should be done next week. I am planning to inspect the work on Saturday, then sign off acceptance and pay the $.

I will post some photos of the result. Anyone who is interested in having this work done here in Southern Cal, email me and I will give you the # of the guy.

The worker is a great sailor who has raced on some transpacs and is now boatless. He offered to crew for me when I deliver the boat Long Beach to San Diego so I guess that is a good sign that he'll stand behind his work!

I wish it was done today's weather is perfect for sailing - sunny, temp about 70, NW wind 13 gusting 17 (only the waves are up - over 5 feet).

The keel bolts go through a piece of plywood that is encased in fiberglass. I don't know how the factory seals the holes around the bolts, but they do need to be well-sealed. If water from the bilge gets inside the fiberglass to the plywood, it can weaken the plywood.

He'll stand <i>behind</i> his work?...more like stand <i>over</i> his work! <img src=icon_smile_wink.gif border=0 align=middle>

This is something that has amazed and concerned me. Due to some small rain leaks that I have yet to find, my bilge is almost always wet. In fact, I poured some antifreeze in there after the boat was hauled. Assuming that Catalina didn't overdrill, fill with epoxy, and the redrill for each keel bolt (because they don't seem to do that anywhere else), I can't see how they expect a wood core to last in the bilge.

Jim: Did your keel guy find that he was drilling through wood?
