Captain Jack Sparrow and his foe fight between two moving ships. The two ships were gimbals moving up and down, left and right, forward and back. Two high lines were custom built that could be operated while on the move. Six operators were safe-tied to the gimbal, allowing 3 men per performer. This was needed to allow performers to be able to run and jump from one cannon to the next and from ship to ship while continuing their fight sequence. CGI was used to place elements on the ship.
