tager If the PO thought it was encapsulated, but it wasn't, odds are he never checked the keel bolts!

deniseO30 this is a



is an oday " encapsulated keel" it's lead within fiberglass.

orientalnc2010 I would like to add my 2 cents to the subject. If any portions of the keel is flaking off or loose then grind down to bare metal and follow west epoxy instructions for applying their product to the keel. Quick summary, once down to bare metal wash immediately with acetone and apply unthickened epoxy to the metal and work in with a wire brush. While this coating is still green, set off but not cured, apply fairing compound. Use epoxy thickened with micro balloons. Its just a powder that thickens the epoxy into a paste that is easily sanded smooth. Then you can apply a barrier coat.
I had great success with this method on a sabre 34. Portions of the keel had failing fairing, instead of spot repairing I took her completely down to bare metal. 6 years later when I sold her the keel still looked great.

stevemac00 I had a little rock gouge in the keel a few years ago. The yard filled and bottom painted - a year later it needed repair again. I ground it out smooth, filled with West mixed with fairing. Then I covered with 2-part Interlux epoxy barrier before bottom painting. Three years later it's still perfectly smooth and coated with bottom paint.

83XT4 Thanx guys and girls,
it's 1994 model voyager #274
it would only be the bottom 300mm that is flaking off, plus the leading edge of the keel.
Definitely not glassing keel. Think the micron balloons faired over exposed lead is what i''l do, then paint.
ANd monitor barnacle growth.
It appears alan's response is what is going on down there.

Well of to the yard
Bye

JohnRPollard Thanks Alan. That's good info.

I suspect this is what the p.o. of 83XT4's boat must have meant when he said that the keel was "encapsulated". I can see how confusion could arise. He should have been a bit more specific and added "in epoxy."

Back to the question, I would say that if the epoxy is intact and still adhering, then simply re-painting is all that's called for. If there are some bare or flakey spots, then following Bill Murdoch's advice to use the International/Interlux method of sealing and fairing would seem like a good approach.

Our boats hav an external lead keel casting that is bolted to a keel sump/stub in the hull. It is the same for any of the Pacific Seacraft models with fin keels (i.e. Crealock 31, 34, 37, 40, and 44). Only the older designs with full keels (Flicka, PSC 25, Mariah 31) and the Dana 24 had internal, encapsulated ballast.
Ironically, there was a question on a ground plane antenna system that had to do with grounding. In answering the question, Steve Brodie responded with an answer that seems relevant to this thread too. Please see the "Ground Plane" thread and the posting I made about 1:00PM today (1-7-10)

wsmurdoch Last year at our fall haulout a 1ft^2 area of 1/8" thick fairing compound on the side of the keel was found to be loose and was removed exposing bare shiny smooth lead. It was repainted with no preparation with Micron CSC. By the time we got to the Bahamas in March, the bottom paint had disapeared from that area of the keel and also (as usual) from the leading edge and bottom of the keel where bare corroded and barnacle root covered lead had been painted over.

This year I had all of the fairing compound removed from the metal part of the keel, the lead ground to a rough bright surface, then following International's recommendations the surface was treated with a wash, 9 coats of Interprotect epoxy, a little fairing was done, and then it was painted with Micron Extra.

We will see how that works.

JohnRPollard Gavin,

What year is your boat?

I don't like the "shipwrights" suggestion to put fibreglass on the external portion of the keel. Sometimes there a small seem is visible between the lead keel casting and the keel stub, but that can be faired with some filler.
