Since you have a deck stepped mast on the coach roof, detecting rot or moisture can be done with a moisture meter. You would likely note the area around the mast base casting to be somewhat spongy if there was water ingress. Our mast step on my 25 mk1 was supported by the midship bulkhead below decks and stayed rather dry for the 14 years we owned the boat. However we never added any deck hardware near the mast and only used the mast mounted cleats and winches for halyards and control lines. Poorly bedded deck hardware can cause water intrusion issues.
