Question

BOTH INTERNATIONAL & INLAND When is "risk of collision" considered to exist?

A) a vessel has a steady bearing at a constant range
B) there is any doubt that a risk of collision exists
C) four vessels are nearby
D) a special circumstance situation is apparent

Answer 1

A risk of collision exists when a vessel has a steady bearing at a constant range or when there is any doubt that a risk could be present. Both options C and D are correct.

Step-by-step explanation:

Under both International and Inland navigation rules, a "risk of collision" is considered to exist in two scenarios:

• A) When a vessel has a steady bearing at a constant range, indicating that the distance between the two vessels is not changing, and a collision course could be underway.
• B) When there is any doubt that a risk of collision exists. It is always better to err on the side of caution in situations of uncertainty.

The presence of four vessels nearby (C) or a special circumstance situation (D) does not by themselves determine a risk of collision. Each situation needs to be assessed based on the specific conditions and relative movements of the vessels.
