A cruise required curtains and shutters to be drawn from dawn to dusk after their captain warned pirates could attack their vessel.
The cruise ship, Sea Princess was carrying 1,900 passengers on a 104-day trip.
This was all due to Captain Gennaro Arma's true concern of a "pirate attack" that was probable if they were spotted.
But apparently the constant reminders about pirate attacks prompted passengers to report any ship they saw on the horizon to the crew, meaning staff on board were taking numerous calls throughout the day alerting them to any nearby vessel.
The measures were taken while the ship was sailing through the Indian Ocean, the Arabian Sea, the Gulf of Aden and the Suez Canal. "Bright lights, which normally signal the presence of a Sea Princess on the ocean, were dimmed or turned off altogether".
Jasinski said the ship played documentaries about pirate attacks on the cabin televisions so that passengers could educate themselves on the risks involved. "In the case of a real threat, those passengers in outside cabins were told to close and lock their balcony doors, then lock their entrance door to their cabin and take shelter in the corridors", Jasinski wrote.
"It was made very clear on the Sea Princess, very quickly, that this pirate threat was not something to be joked about", Jasinski wrote in the essay published Monday.
One of the most dramatic incidents happened in 2008 when the Nautica cruise ship was sacked upon by two pirate boats in the Gulf Of Aden, according to the IMO.
Princess Cruises told the New York Daily News that any measures taken on the ship were simply done "out of an abundance of caution."
While there was no direct or specific threat from pirates, the measures were taken by the crew as a measure of precaution. The cruise holiday was nothing that they had ever imagined.
She said the Sea Princess was equipped with hoses that could be sprayed at small ships, and a sonic boom that could knock pirates off ladders.
The ship never encountered any real danger, and spokesperson for the cruise told The Telegraph, "Any measures aboard Sea Princess were simply taken out of an abundance caution and not in response to a specific threat and are common to worldwide shipping sailing in the region".
