Web1 Jul 2016 · Mainly such roll occurs when the ship is either in the following sea or head on sea. Sometimes the pitch motions which resonate with the sea waves might be responsible for a dangerous roll condition. Hence, a modification of the pitch behavior of the ship might help avoid such dangerous roll motions. The vertical/Z axis, or yaw axis, is an imaginary line running vertically through the ship and through its centre of mass . A yaw motion is a side-to side movement of the bow and stern of the ship.
