W42 Rudder Cracks

    Hi Bud, Everyone,


    Well while doing engine work and other electrical projects getting ready for the new engine, I had the yard sand the rudder in order to put a barrier coat on it. The surface " bottom"  paint and and underlayment was flaking off and there ares blisters in areas. Once the bottom paint was removed numerous cracks were revealed throughout the rudders sides. It looks like the previous owners had glassed over the rudder. Gel coat is visible in areas under the re glass and the glass that they put on can be ripped off in places. Moisture readings on the starboard middle side are very high in the red compared to the port side which are in the green. I thought that perhaps it would be a little better being that the vessel has been on the hard for quite a while. I believe that the boat may have spent time in Alaska. Perhaps that owner had the boat out of the water and if the rudder had water in it and temperatures got below freezing that perhaps that may have caused the cracks. 

    Has anyone had similar problems. I may contact Foss Foam Products and see if they have the mold for the W 43/42 rudders. I will try and post a photo. I may cut out a core sample on the starboard side and see what it looks like. The hammer test reveals many delaminated areas as well.

    Thanks,


    George

    P.S.  I did talk to Dave at Foss Foam Products this morning and he is pretty sure that they have the rudder mold and will get back to me Monday with information b/c their computer was down when I called.
