hit something, broke and was abandoned at sea.

I think Rob sailed it some years ago.

Mighty boat on video.

Its built looks very much engineered.

Any weak structural points experts can point to ? 

The main hull departed from the ama looks quite improbable unless the ama itself broke off.

 I hope they find it and report back the damage to learn from.

Sad.
