Chapter 3 – Visibility

  3.1 According to SOLAS chapter V, the view of the sea surface from the conning position should not be obscured by more than two ship lengths, or 500 m, whichever is the less, forward of the bow to 10° on either side under all conditions of draught, trim and deck cargo. National deviations may exist and should be taken into consideration as required dependent on the intended voyage.

  3.2 No blind sector, caused by cargo, cargo gear or other obstructions outside of the wheelhouse forward of the beam which obstructs the view of the sea surface as seen from the conning position, should exceed 10°. The total arc of blind sectors should not exceed 20°. The clear sectors between blind sectors should be at least 5°. However, in the view described in 3.1, each individual blind sector should not exceed 5°.

  3.3 The following formula can be used for calculating the bridge visibility:

 Where:

  • KCKS Horizontal distance from conning position to position 'S'
  • KSKP Horizontal distance from position 'S' to position 'P'
  • AC Airdraft of conning position
  • A S Airdraft of position 'S'
