Carbon Rudder Post

I own a ''77 Newport 30''. Absolutely love it. Two weeks ago the rudder post began to slip in the rudder. I found over the years that the straps welded to the post that are held in place by the foam core finally sheared off from corrosion. And now the post just turns.

So I''ve done a bunch of research and decided to redisign the post (Very poor original design) and I''m very happy with the new look I''m going for. (For those of you interested, I''m using the NACA0012 airfoil design).

Here''s the beauty, I wanted to use Carbon Fiber (CF) instead of the same old Stainless post so I never have to worry about corrosion again. I found a company that has 4 tubes that are the exact Outside Diameter (1.8785 - 1 7/8) whose modulus strengths and torsional strengths are very close to the old SS post.

Now I''m mostly a bay and coastal cruiser so I''m not going to worry about having a post that can withstand typhoon weather. The two composit engineers I''ve spoken with fully believe that the CF replacement will be more than adequate.

So, anyone want a Carbon Fiber post O.D. 1 7/8" by 60". The guy is asking $125 per piece.
