I am looking into buying a 1977 Hunter 30'. Today I had a survey done. One thing made me worry. I was told that the steel ( I beam ) mast step in the bilge needs replacing. Someone told me that it's and easy job and that I can do it myself very easily. For some reason it looks like a big job to me. Has anyone done it in the past? Any sugestions? The vesel overall is in great shape for its age.
