[Alberg30] Gooseneck problem

[R.C. Alley]

Lanocote, for the uninitiated, is a lanolin based product; pure lanolin from your druggist/chemist works just as well--but tends to run when it gets really hot!!!!

  AND use Lanocoat (or Lanocote) to help prevent seizing, galling, and corrosion between stainless and aluminum.
  (no, not connected, just a happy consumer)

    I had this problem on the portside ear attachment to the sliding fitting on the mast. Unfortunately, the "easier" alternative for you (lashing the sail in place) is not "better."  Having it repaired is probably cheaper than replacing it--at least it was here.  The problem is galvanic intergranular corrosion in the aluminum--which gets its start because of the stainless shackle.  I would check all of the other parts where stainless bolts run through the gooseneck as well.  As long as the corrosion has not gone so far as to make the repair impossible, you can continue to use the part once repaired.  You might want to look at fitting  nylon or teflon bushings.  They would have to be replaced occasionally, but can significantly reduce future galvanically caused corrosion, which will continue as long as you have stainless in contact with aluminum.

      The attachment point for the mainsail clew on the gooseneck has broken off,too many years where a stainless shackle was left in situ.The obvious solution seems to be to remove the gooseneck, have the aluminum casting built up by a welder,and redrilled.Does anyone know  an easier alternative?
