A new rudder under construction

The original rudder on ETAK sits in my garage.  I had no idea that the "termites of the sea," the infamous teredo worm is not a worm at all but a bivalve mollusk.  When these shipworms bore into submerged wood, bacteria  in a unique organ that is a gland permits them to digest wood fiber which is what happened to this rudder.  The epoxy coating was not thick enough on the original,  and once they had access to the wood, in they went! The new rudder will have a heavy coating of epoxy fiberglass to protect it from these critters.
