Wow, I've never seen that happen, but it is a good thing that it did and you weren't hurt and the mast wasn't damaged.

Like everyone says, just seal it well (4200) and drill new holes for SS or Monel rivets.

I wish I had been thinking because we were cat sailing at Cedar Key yesterday and that might have been within your range. I may be back down here in a few weeks. Probably Sept 19-20 weekend.

You might think ahead to the Cedar Key Regatta coming up in October (10/24-25). You don't need to be a racer to participate. It will be low key and I think mostly H16 and TheMightyHobie18 folks with a few of the remaining Prindles.
