If a ship is poorly constructed, the bow visor can be damaged and break. It happened before
You were an idiot to try and replicate the disaster with a bunch of sleeping crewmen who had no idea that you, the 'safety at sea' man, was being so reckless as to test a hare-brained theory and gambling with their lives in the meantime
No wonder you were fired and stripped of your 'safety at sea' credentials. If I were on board, I would have thrown you over for that pointless stunt given half a chance. To hell with you
