Re: Helms 24 core repair under mast, need advice
On my boat the compression post is supported by a stringer. No idea what type of wood was used for it, but it was tabbed, not encased and the wood had rotted away so completely that it took me a while to realize it had been there. Repair was time consuming but not overly complicated. Would have been easier with the mast down though.
Symptoms were the depression around the mast step and associated crazing, and ripples in the bulkhead.
Looking at pics and the schematic on sailboatdata.com, it looks like your compression post may go all the way to the keel, so the base could have rotted and compressed.
