- The view of the sea surface from the conning position is not to be obscured by more than 2L or 500m, whichever is less, forward of the bow to 10° on either side for all conditions of draft, trim and deck cargo under which the particular vessel is expected to operate.
- From the main steering position, the horizontal field of vision is to extend over an arc from right ahead to at least 60° on each side of the vessel.
- The horizontal field of vision from the conning position is to extend over an arc of not less than 225°, that is, from right ahead to not less than 22.5° abaft the beam on either side of the vessel.
- From each bridge wing, the horizontal field of vision is to extend over an arc of at least 225°, that is, from at least 45° on the opposite bow to right ahead and from right ahead to right astern through 180° on the same side of the vessel. The vessel’s side is to be visible from the bridge wing.

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°.
