Hi Jeff, it does not seam to me that the Hanse rudders are made of two pieces glued together but from a single molded piece:
"Polyester glue is added on all contact places then the rudder stock is carefully glued to the blade.The form is then filled with PU foam which expands dramatically and fills up any free space in the blade. After a few hours rest, the mould is opened and the blade edges are finished by hand."
You can see photos of an open mold here:

Do you have noticed that the ruder is scrapping on the hull when it rotates and that there is not any clearance between the hull and the rudder?
There is normal to have a clearance between rudder and hull. Here a rudder from another Hanse:
The fact that there is not one and the rudder is scrapping on the hull suggests that all system was violently pushed up and that could have resulted in a pressure crack.
My guess is that happened when the boat was put on the truck, or taken away from it unless that had happened when the boat was grounded in Sardinia.
The rudder could have hit a rock or if it is a swallow draft version, with the rudder almost at the same level of the keel the waves that existed when the boat grounded could have moved the boat in a way that the rudder could have touched the ground violently even if that was not noticed aboard. One thing is the keel touching the ground and other is the rudder, the consequences are far different.
