B. only to fog

C. to any condition where visibility is restricted

D. to visibility where you cannot see shore

Answer:

The term 'restricted visibility' used in International and Inland maritime navigation rules refers to any condition where visibility is compromised and is not specific to any particular circumstance.

In the context of maritime navigation rules, both International and Inland, the term 'restricted visibility' refers to any condition where visibility is restricted. It is not limited specifically to visibility of less than one-half of a mile or to foggy conditions, or situations where you cannot see shore, but rather is a general term that encompasses all circumstances where visibility is compromised due to various weather-related or environmental factors that could affect a vessel's ability to navigate safely.

When navigating in conditions of restricted visibility, mariners must take extra precautions to ensure the safety of their vessel and those on board. This may include reducing speed, sounding fog signals, and keeping a close lookout for other vessels or hazards in the area.

It is important for all seafarers to be familiar with the concept of restricted visibility and to follow the appropriate navigation rules and procedures to prevent accidents and ensure smooth sailing even in challenging conditions.
