Originally there were 12 boats when the ride opened, but this was reduced to 11 when one of the boats was converted to clean the canals. By the end of the life of the ride, there were only 5 boats operating. The reason for closing was because of the cost to keep the boats running. They constantly had issues with their natural gasengines and guidance system. Originally the guidance was done with an electronic system but was changed to use water propulsion to turn the boat. Eventually the boats were removed and sold.
