I don't know if there was a report, but it must have been a real Doozy for the shipyard to explain that one. I was reading about that ship yesterday in my copy of Mark Warren's Shipbuilder Volumn Two, where he put the origional Shipbuilder artical on page 27. What added to the embarrassment for the shipyard was that it happened in front of 4000 guests including a senator and some of the Italian aristocracy.
The ship itself was written off as a total loss and scrapped in situ.
If you have a chance, add Bonsall's 'Shipwrecks of the 2oth Century' to your list. It has fascinating pictures of the launch and then- disaster!
It is funny watching the people in the row boats watching the ship turn over right before their eyes.
