RE: [Cal_Boats] 33-2 Damiana's Recent Yard Visit [1 Attachment]

I have my cal 33.2 hualed out and am currently in the process of having the entire lower previous coatings ground down to the glass. Then several new coats w a barrier coat will be applied. I have all kinds of projects going on. Im trying do decide if I should replace my strut, glass it or leave it alone. It has a good amount of corosion damage but nothing els does?. All of the other through huals are original, bonded and it good shape. That strut is flat ugly though. Has anyone changed one or know how big a deal it is?MatthewSv Warm winds 1986 Cal 33 From: "Christopher Thompson ra… [at] yahoo.com [Cal_Boats]" <Ca… [at] yahoogroups.com> Date: 3/22/17 11:55 PM (GMT-05:00) To: Yahoogroups <ca… [at] yahoogroups.com> Subject: [Cal_Boats] 33-2 Damiana's Recent Yard Visit [1 Attachment] [Attachment(s) from Christopher Thompson included below] Hauled the boat a couple of weeks back. While the yard was pressure washing the bottom, large pieces of paint and filler began popping off of the keel. My wife and I spent the day chipping the paint off of the entire keel. As you all know, the yard list grows the second you pull the boat out! The lead of the keel was in very good shape and I was impressed by the care that went into the molding of it. We scuffed the surface and applied 2 coats of a 2-part epoxy made for the purpose. I spoke with one of the yard foreman and he asked if the keel was electrically bonded and I told him that everything appeared to be bonded on this boat. He stated that they have seen boats with bonded keels lose the paint from that surface and that it is a possible indication of an electrical issue (it is also possible that the keel was not prepped properly for the paint). We walked the rest of the metallic objects below the waterline and noticed that all of the bronze thru hulls had a dark, scaly buildup around them. These are bonded. The shaft strut is also bonded but it has a zinc attached. It was pristine. I have read articles on bonding and have seen strong arguments for and against bonding. It seems that East coast boats are more likely to have extensive bonding systems to deal with the higher potential for a lightning strike. I have started to review the wiring on my boat in an effort to expose any problems ( I found several wiring issues on my last boat). I have removed the bond wires from the thru hull fittings and the diver and I will keep an eye on them. Have any of you experienced issues related to bonding?Chris 1988 33-2 Damiana

My strut was in really bad condition and was pulling out of the boat when we hauled in St. Peterburg, FL about 2001. The yard cut out all of the glass around it, braced it in place to maintain the alignment, and then reglassed the strut into place. They braced it somehow to maintain the alignment while doing the glass work. Has never been a problem since. They put a LOT of fiberglass in that repair!

I'm assuming that you had a zinc on the strut?

Our strut was painted when we first got the boat and it was starting to corrode. We stripped the bottom paint and put a pancake anode on each side. No troubles since.
