Panting refers to the tendency of steel hull plating to flex in and out like an oil can being squeezed when a ship is pitching. This occurs when a ship is making headway in waves. Panting creates significant stress on a ship's hull.[1] It is potentially dangerous and can result in flooding and the separation of the hull and deck. The British battleship HMS Rodney suffered significant leaking from panting.[2] Addressing panting is an essential component of ship design. It is typically countered by reinforcing the bow and the stern with beams and stringers.
