Colchide came out the water last week and I noticed that the rudder had some delamination cracks on the trailing edge. It has a 12mm central oak core and a further 12mm of marine ply on each side, totalling 36 mm. To stop water ingress in the future and so I can leave it in the water all the time (at the moment I remove it from it’s stainless steel cassette at the end of every sailing day), I am thinking of sheathing it. The local glass fibre specialist says he can sheath it with 1 mm coloured mat, then resin, which will definitely stick to the wood, and it will be completely waterproof. He quoted £80.
Any thoughts please?
