I have yet another J24 with wet core. I have read the West systems guides and plenty of threads on this forum and others and they have all been very helpful. The only thing I'm not sure about is what to replace the wet core with. My boat was built in 1988 and was cored with balsa. Should I replace it with balsa or something else? I would like to use something that won't absorb water in the future. My boat is a little heavier than class minimums so something lighter than the original core would help get the boat down to weight. Any input would be great.
