Navigational Visibility Law and Legal Definition
Navigational visibility refers to visibility that affects vessel's speed. It is measured with reference to the distance within which a ship could be brought to a stop in the water, before the course of any vessel emerging from the fog on either side would cross her projected course alongside the fog bank at its nearest point.[Silver Palm, 94 F.2d 754, 767 (9th Cir. 1937)].
The term restricted visibility refers to any condition in which visibility is restricted by fog, mist, falling snow, heavy rainstorms, sandstorms, or any other similar causes.
