Looking to buy 1983, but lower 3" of bulkhead has some dry rot. how to fix? Is it a structural issue? If mast support post is wood(teak?) would I expect rot there too? Any other issues we need to be aware of. The boat has been in fresh water most of its life (only 1 1/2 years in salt water. Seems very well cared for, is a dry boat with minimal leaks. Stored over one winter with stbd port left open which allowed water to stand in bilge.
