Points to pounder for sheer of ship:
  • Most of ships, the intersection of the deck surface and the plane of symmetry is a curved line with the concavity upwards. Usually, that line is tangent to a horizontal passing at a height equal to the ship depth, D, in the midship section, and runs upwards towards the ship extremities. It is higher at the bow. This longitudinal curvature is called sheer.
  • The deck sheer helps in preventing the entrance of waves and is taken into account when establishing the load line in accordance with international conventions.
