A pirate ship is a type of amusement ride based on pirate ships, consisting of an open, seated gondola (usually in the style of a pirate ship) which swings back and forth, subjecting the rider to various levels of angular momentum. A variant where the riders must pull on ropes to swing the ride is known as a swing boat. The first known predecessor of the ride was invented by Charles Albert Marshall of Tulsa, Oklahoma between 1893 and 1897. This ride was originally called "The Ocean Wave". The Ocean Wave was first used in the Marshall Bros Circus in 1897. The circus was run by Charles and his brothers Mike, Will, Ed, friends, and family. Height requirements Height requirements for this type of ride vary from park to park. For example, Hersheypark, which has a Huss Pirate Boat, has a height requirement of or more to ride, while at LaRonde, which also has a Huss Pirate Boat, riders must be or taller. Huss recommends that the lowest a height requirement should be is , but parks can make it higher if they choose to.
