Wanderer, if i
recall there is a large
marine consignment yard near Foster
rigging in Quincy. Mass
Marine Parts? Perhaps they have a mast you can replace it with?
Also, there is a man named Dwayne Melcher at Admiral Hill Marina in Chelsea who has
refit and scrapped a few
boats. He may know where you can source a used replacement.
Finally, consider consulting an
engineer and machinist to repair/sleeve it. This is probably the most cost effective approach.
