It appears to be the IMF mast.
We can wait for Roger to respond, but if that happened to my mast, here is what I would do.
After taking measurements to get the spreader positions recorded, I would remove the main sail and furling tube assembly. Remove the spreader brackets. I'm do not have an IMF mast but the spreader brackets aren't through bolted through the mast from side to side like some older standard masts I've seen.

Then contact a local machine shop or welding shop. Have the damaged areas cut out or cleaned up. Stop drill any radiating cracks, then TIG weld them up.
Then TIG weld 3/16ths" or 1/4" plates over the damaged areas/holes, and remount the spreader brackets. Survey how you'll remount the brackets before the welding though.

Just my thoughts.
