Re: Jason 35 with balsa deck core damage.
It really depends on the size of the rotten core sections. If you are just talking about little rings around bolts, then you can just clean the rot out with a hook, and fill the void with moderately thickened epoxy. If we are talking about large sections, then you have to cut one side of the skin out, replace the core, then replace the skin you removed.
Either way it is completely repairable, the question is how much it will cost, and the only way to know that is to have a yard quote out the work, assuming you can't or don't want to do the work yourself.
