Swing boat

A swing boat, colloquially known as a "shuggy boat" in Northern England, is a fairground ride in which pairs of riders pull ropes to swing back and forth. A similar ride called a pirate ship swings in a similar motion but without the rider pulling on ropes.
Swing boats were one of the earliest fairground rides, common in the Victorian era. The Beamish open-air museum features an example from the 1830s, named "Skylark". The boats were originally powered by hand, but steam-driven versions began to be introduced in the 1880s.
Examples of Victorian-style manually-operated swing boats are still popular and are generally seen in traveling "period" fairs.
