Catalina 25 Keel

The keel was unprotected during her former use other than a few layers of bottom paint. The concept for the keel was to
eliminate the rust and prevent any more by protecting her from the salt water at all cost. It was decided to totally encase her in
Fiberglass. Then fair her back using the correct air foil templates. Also to bond in a stainless steel bushing that the pivot pin
would rotate in. Just for info she was cast in Mexico and weighs a mere 1500 lbs. Questions and comments are welcome.

The pivot hole will be repaired with a stainless steel insert. The insert will be bonded in place using epoxy prior to applying the fiberglass covering to the entire keel.

First layer of West Systems epoxy thickened with 410 fairing compond.

 

 

The fairing compond will be used to get keel back to basic shape and dimension. It will be applied thinly on the surface so no sanding is required. Do not want to sand through primer and metal prep exposing metal to the air.

 

Once the shape is attained, the fiberglass will be applied. Then the keel will be faired to desired shape and finish.

 

Four applications of filler over the surface should be enough to fill all the voids.

 

Bottom of keel had a fair amount of corrosion. This area will get extra layers of fiberglass in case of acidential groundings.
