I recently pulled the mast from my new to me 76 Ericson 35 mkII. It has pretty bad corrosion where it contacts the deck step. It only extends for the first inch up from the base. There is also a couple small cracks in the same area. I would like to simply trim 1" off the base of the mast then tighten up the standing rigging and move on. Has anyone done this and what were the results?
