Hello Will,

The Divinycell foam used in the fairings is usually "H-80".

One problem with changing the gudgeon and pintles from the original SS to the newer fiberglass is that the rudder is different.  The newer style Pintles will not fit on the old style rudder  The old style rudder could possibly be modified but it would not be an easy job.  If you are in need of new SS gudgeons, I may be able to find some.

The fairing can, and has, been done around the SS gudgeons a number of times.  The main differences are 1) most of the fairing is done using 1/4" foam instead of 1/2" foam.  2)fairing is also done to the rudder. 

Good Luck,     Dave

Thank you both for your replies. My rudder is construction is from the transitional period (1974,Hull #174) where it is fitted with the stainless gudgeons and pintles, but has the recesses for the bronze pintles. These have worked for the 20 years I've had my boat, although I needed to replace the pintles about 8 years ago due to corrosion, inspite of the fact that they were never without zincs. I've never been particularly pleased with the setup, and thought that if I go forward with the keel mods that it would be a good time to change to the glass at that time. I was reading one of your posts from 2014 where you had a new rudder built, and said the builders could also fabricate the gudgeons. Wondering if this is still an option?  I was also able to locate 1 1/4" silicon bronze rod from onlinemetals.com. that could be machined to work. What are the options?

Will
