I can't believe a person can be so stupid! Drunk is no excuse. Like Kmathi said, he was sober enough to go through all the steps to enter a restricted area and deploy the anchor.
I hope he pays a huge price for his stupidity.
To prevent other ignorant people from pulling a similar trick, maybe the ships should have alarms or some other signals when an unauthorized person enters a "restricted" area. This incident could have had expensive or tragic consequences.
