You guys are all aware that a bunch of guys that have never seen Charles' boat have decided that he has a swing keel problem.

Charles, find the leak before you do repairs that you may or may not need.

OK since we are wondering on the subject of hard to find leaks, years back I kept getting water on the floor in the area of the head (no it not what your thinking, it was lake water, really it was). This would only happen after a hard sail, and I figured while I was heeled over, the water was working its way up there from the bilge. It took years of checking this and that before I finally found the location of the leak. On my SK there is a pad eye on the bow of the boat for trailing (I’m sure it has a proper and more bettererer name, but pad eye will work for now). This is bolted through both the hull and the inner liner, and can be seen by looking through the inspection port at the front of the “V” birth. What you can’t see is the gap between the two sections. I finally found that the pad eye wasn’t as tight as it should have been and when sailing in high winds, water was being forced up the bow, and entering through the fixture. What made it hard to find was the water flowed down between the hull and the liner, and could not be seen. After re-bedding and retightening the pad eye the leek went away.

Catalina didn't put any limber holes in between compartments to accommodate draining? Seems like a design flaw to me, all boats get some water into them through seepage, bad/old bedding, getting pooped, even condensation over time. Seems like it's a relatively easy fix if you can get a drill into the various compartments, but a pain to do it right (overdrill, epoxy, redrill, etc.).

Not on mine they didn't. However, mine is hull #29 and I figured they changed a lot of things along the way. I would suppose that it would have been corrected by 1980 but I don't know.
I laminated a piece of 17oz Biaxial over the location I wanted the limber hole. Then I drilled through the tabbing into these compartments and epoxied in a short piece of 1 1/2" PVC pipe. I did it mostly for ventilation to keep things dry. A LOT of water drained out once I drilled the holes with a hole saw. I've updated the pages so click on my home page and you can see where I cut the limbers.

Don Casey says to use a leaf blower to pressurize the boat and go over the outside with soap bubbles. My luck, I'd blow a window out and I'd have even more to do.

What we have here is a group of fellow sailors noticing that Charles has presented with a problem and its symptoms, less PHOTOS. that we have experience with. We merely have offered our support for his problem, remembering the feelings that we had when faced with the same situation. Suggestions have covered just about every possible cause and solution. I think Charles is in a better position knowing the span of difficulties and solutions that we've shared over not having heard from us at all. I say this including your input to not over react.
