Hi All,

I'm posting three of the pics that I took of the wing keel, two with visible cracks, one with what looks to me like bedding compound. I tried to make these smaller so they would load faster without losing too much sharpness. I may or may not have been successful in that regard.

Thanks ya'll,

Ben

Looks like a pretty bad install. I'd be fried if somebody did that to my boat, wouldn't care how nice they are. You do a job right or you don't do it at all. If the installer didn't have the tools to do the job, he should have said so. Then allow you to find someone who does and can.

I think that the fact that the joint has caulk over most of it says a lot about what the guy who did the work felt about its structural integrity. There should be no caulk involved in this at all. Nice pics BTW, and loaded here about as fast as text, I'm just beginning to use a digital camera and figure out how to use it to ad info. Took pictures of a keel hole in a Soverign today. Dave

Dave, where do you see caulk? Are you talking about the pinkish stuff around the forward edge on the top picture? I guessed that was the bedding compound.

In the center picture the crack with the pieces of material across it looks like caulk (5200). Is it? Epoxy usually breaks clean (like in the bottom picture) unless there is glass fiber in it. Dave

I see what you're looking at now. I'm not sure what that is. I assumed it was a fairing compound the installer used, but I don't know specifically what he used. Is caulk (5200) a bad choice for this application?

Yes -- and sized nicely so they appear on one screen without any irritating horizontal scrolling to read all the messages. Thanks for being considerate.

5200 is an adhesive caulk for semi-permanently attaching deck hardware and other things you don't want to remove, but that don't rely on it for significant mechanical strength. But it won't do anything to help bond a 1500# piece of lead to fiberglass. That bond should be the combination of bolts for vertical strength and epoxy to prevent any possible horizontal movement and to truly bond (not just stick) to the hull structure. 5200 doesn't come close to doing that.

Thanks Dave B. BTW, I didn't realize this, but the weight of the wing keel, according to Catalina's instructions, is 1,850 pounds. Wow. Considerably more than the swing keel, which comes in at 1,500 pounds if I'm not mistaken.

Dave B. has it right, there should be no caulk involved in this just smoothly applied epoxy fillets that are not too big. Good luck Dave
