this is NOT balsa cored hull....only small deck areas have core...much of deck reinforcer with solid fir.the shrouds are aircraft aluminum &should last longer than rest of boat...as long as fastings inside bulkhead which are wood still intact...the hull built by belleville marine ,,one of founding companies of c&c mfg.... specialized in centerboard boats example corvettes....,belle marine made a lot of aircraft industry aluminium parts especially wings i believe...ALSO RUDDER frame &rudder post probably aircraft aluminum...even battery wire was welders wire ....centerboard was bronze casting...as is usually the case these features did not continue to be used because of cost in mid 1970s...except boat s from custom shop..stainless steel was the cheaper replacement in many cases...
