Cracks in Mast w/ Photos

[dptransom]

Brion - I have a 1981 Morgan 382 with a Kenyon mast. I'm preparing the boat for offshore cruising - first to the Caribbean. After that, we'll see. I pulled the mast to replace the standing rigging and found two cracks at the compression sleeves for both the lower and upper shrouds. Aside from these two cracks, the rest of the mast seems to be in pretty good condition. There is some corrosion on the masthead welds, but it looks minor. Obviously, I cannot see what is going on inside the mast. A few inches above the lower shrouds are the spreaders. A few inches above the spreaders is an original sleeved seam. Are cracks like these repairable? Welding?

Here are some photos of both cracks:
