I had called the listing broker on that same boat (1998 in Redondo Beach), and it's interesting because I specifically asked about gelcoat crazing and was told it "wasn't an issue on this one". They seemed to believe that the likely issues would be with the rig and potential underuse of the engine, no mention of moisture issues with the interior. It is a shame it was let go, these boats seem to be very well-built.
