Opened in 1984, the Sea Serpent was the first boomerang-style coaster built in the United States and is located on Morey's Mariner's Landing Pier.
Sea Serpent consists of a single train with seven cars, capable of carrying 28 passengers. The ride begins when the train is pulled backwards from the station and up the first lift hill by a catchcar. After being released, the train passes through the station, enters a cobra roll, and then travels through a vertical loop. After being pulled up a second lift hill, the train is released to head backwards through each inversion once more, making the total amount of inversions per ride six.
