Climb aboard this terror-filled cruise, which sails into the open ocean at night -- if you dare -- to face the inmates of Psych Ward Seven, who were confined to this particular ship, the country's first floating asylum, in the 1930s. This new Halloween horror attraction from the creators of L.A.'s creepy Haunted Hayride is the only one in the U.S. that takes place entirely on the water, with three separate levels of interactive scares. Below deck, explore the abandoned hallways of the asylum's treatment area, with its electroshock therapy rooms and morgue. The middle deck provides a possible respite, where cocktails are served with an Art Deco ballroom vibe -- though no part of the ship is completely safe from scares. Finally, there's the top deck, which features an immersive execution experience. And just remember -- there's no way off the boat for its 75-minute sail, and nowhere to hide.
