Repair advice requested

[Sacto Dave]

Greetings fellow C-22 owners!
End of last summer the sun hit my boat just right and I saw some defects that concerned me. Not sure what they are, other than fractured gelcoat(?) or best way to repair.
Any tips would be appreciated.

Not sure what they are, other than fractured gelcoat(?)

Looks like the result of a few good dust ups inside the boat. Is there something exerting an outward force on the hull because the close ups of the defects look to be protruding.

If no obvious cause of the defects is found, my choice would be to add several layers of glass/resin to the interior of the hull under the defect (hopefully hidden) equal to the height of the defect or greater. Then dish out the defects on the outside of the hull while ensuring you see no cause for the defects in the glass and then finally coat with gel coat.

The hulls on the older boats was pretty thin, that's why the racers like them. That gelcoat looks pretty worn, you can clearly see the laminate beneath it.
