thanks everyone for the inputs.

Allan, nice to hear from you, hope you're doing well.

I have checked both Southshore and CCI about replacement, Southshore sells the 
"original" rudder for 4500$ like said Francois, and CCI can make a new blade 
for 3000$ if you send your post, would be more with a new SS post or carbon is 
offered two.

I could but will not this job myself, we have a very good guy around that does 
composite repairs and custom fabrication, I have no doubt the new rudder will 
be very well made, better than new in fact, and reliable and a lot 
cheaper...But since I race the boat I want to be sure the profile is right so I 
want to have the right numbers to give to the builder. 

with no mold and with both sides profiles altered, he will probably have to 
shape a foam core and laminate over, the key will be to have the core right to 
minimize the fairing and keep the weight down. The actual one is so heavy... 
Probably wet and with a lot of putty from previous "repairs".

I might even ask CCI if they could just sell a CNC milled foam core in two 
pieces that I could put together minimizing the shaping effort and trouble to 
get it right. That seems to there construction technique.

it was interesting to see the file with the sketch of the 37+ rudder. It looks 
like the profile goes tapered  from 15% at the top to 11% at the tip. it makes 
sense and I will check mine to see if I can find the same variation. I would 
love to have an elliptical shape if I wasn't worry it would affect my rating...

I will check with the museum to buy the plans and hope to find answers. 

thanks.

Bruno
