I owned a J30 that I trailered to regattas. It had a 46 ft keel stepped mast. I was able to become self sufficient in mast stepping using an old broken mast I found in a boat yard. I repaired the old mast by splicing it back together. I could set this lighter mast up on deck and guy it off then use it to raise my mast. It worked well. I kept this mast stepping mast stowed on my trailer.
