A rescue plan was put into place. I had the whole cuddy inspected and removed several pieces of wood that were rotted. Maybe rain water had seeped in but the wood were glassed with epoxy and glass cloth. The next logical explanation from my timber merchant friend was the few pieces of wood that rotted had been cut from near the bark of the tree and as such it is vulnerable to rotting. It proves that my experience in selecting the meranti wood had not been good!
Because the boat had been built strong and well when the damaged wood had to be removed some of the plywood came out with it!
I cut away most of the plywood leaving only the structures . Another piece of marine ply will be laid on top of this.
