This evening was productive. 

I managed to add the Uni-directional carbon fibre to the port side of the centreboard.

I also laminated another knee.

  
And also covered the port side of the rudder with epoxy mixed with graphite powder (west system 423) and a little colloidal silica (west system 406). This was a big step because now I can’t see the wood grain or the Kevlar weave pattern. All that remains is the shape of the blade, which is looking good.
