Seems like as the captain you would bring the ship to full steam and go hard rudder and count the degrees per second of turn the thing was capable of as a matter of course on a new ship. Kind of ridiculous to not know the performance envelope of the vessel you are responsible for. The captain was an experienced captain I tend to believe that he wasn't given the information and likely the spotter was paid off to cause the thing to wreck to take out the VIP passengers sailing to NY to kill the Fed Reserve before it was chartered. The wireless operator may have got the message but that is no proof that the message made it to the captain.
