12. Pirates Are Real
While most of us think of pirates as fodder for fantasies, in actual fact they are very real. Modern pirates are no less scary than they’re romantic counterparts. While there have been no successful attacks on cruise ships, that doesn’t mean it couldn’t happen. Ships train crews to deal with potential attacks. They have water cannons for such occasions, but may also have Long Range Acoustic Devices (LRAD) for the same situation. LRADs emit sounds powerful and painful enough to deter pirates from attack. One ship learned the effectiveness of an LRAD firsthand in 2005 when they used it against incoming pirates.
