The mahogany toe rails which are original to the boat have developed some bad places probably due to water and dry rot underneath which has cause yellow bubbles in the varnish. I was wondering if the boards have to be replaced or just stripped and refinished. If they need replacing I was wondering if drawings exist detailing the dimensions?
Is the toe rail rotten, soft and punky or is it just that the varnish has let go of the wood ? If it's just let go, stripping and refinishing is the ticket or you can spot repair it to get by.
I tried spot repairing a few of the areas that the varnish had bubbled up and let go , but a week or so later on a 90 degree day more bubbles appeared from underneath the varnish. The wood is not soft but I think water is somehow either getting underneath and during evaporation the bubbles form from the H in the H2O?
