That's what happens when performance and weight saving are on top of the design principles (not structural integrity) = for racing and coastal sailing

OK good analysis so far but still, deeper questions need to be answered.
The top tip of the rudder created the damage to the hull. Apparently a sudden movement of the rudder post to the aft was evident to create this puncture..
That movement involves a lot of shock loading of the rudder shaft and being absorbed by the rudder shaft upper bearing or bushings.

Were these bearings checked for cracks..? What about the rudder shaft possible hairline cracks, not visible to the human eye.?
You need to have this checked with a non destructive crack detection system like Magnaflux and or die penetrant etc..

Keep in mind that "Sailing Hilma", skippered by a Swedish couple, lost their rudder in the middle of their Pacific Ocean passage. They had no knowledge of a UFO collision.
However they found out that the previous owner ran into some issues with a collision or grounding affecting the rudder..
The rudder loss happened way later in time and is a typical "fatigue" issue that is accelerated by hairline cracks.. I assume the shaft is SS and this material has not much elastic resiliency..
Not trying to scare you but, please go way deeper in the cause and effect analysis..In my days we used to call this a FMEA or Failure Mode and Effect Analysis..
Good Luck

Nice work carefully removing the soaked balsa core. We should talk about the kit boats I'm building. Would like your insight into the problems with dinghies for cruising sailors. I intend to design a much better, affordable and easy to repair dinghy.

Hey guys great video as always, it wasn't clear to me but you are planning a few layers of glass on the outside of the hull as well I hope using at least the 12:1 scarf and overlapping layers with 50mm overlap each time to ensure structural integrity. Glad you have the access to materials and support good luck

I love how technical this video was. I feel like this is information that anyone could find utility in knowing!

Looks like you’re able to find support in this remote Brazilian town. Brazil with such a gigantic coast line doesn’t have a significant sailing tradition.
Well done so far!!

So glad you found the leak before it was too late and that you were able to find a port/marina with what you may need to fix it. By now you might be already sailing, if not, hope the repair goes smoothly. Cheers
