Aluminum mast damaged

[Brion Toss]

Hello,
We'd need to see pictures, but it doesn't sound good. A hole that big isn't the issue; halyard exits are much bigger. But I'd be amazed if the hit didn't create a dent or crease much bigger than the hole, and that could be a big problem. Also, any force sufficient to punch that hole could easily have impact-loaded other components. Be very, very careful with this one.
Fair leads,
Brion Toss
