Question

In fog you observe your radar and determine that a risk of collision exists with a vessel which is 2 miles off your port bow. You should?

1) Hold course and speed until the other vessel is sighted
2) Stop your engines
3) Sound the danger signal at two minute intervals
4) Take avoiding action as soon as possible

Answer 1

To safely navigate in fog and prevent collisions, take avoiding action as soon as a risk is detected via radar, conforming to the COLREGs.

Step-by-step explanation:

If you observe on your radar that there is a risk of collision with another vessel that is 2 miles off your port bow in fog, the correct action is to take avoiding action as soon as possible. According to maritime navigation rules, when a risk of collision is determined, a vessel should not wait until visual confirmation before taking action. Option 4, to take avoiding action as soon as possible, is the most appropriate and safe choice. It is critical to adhere to the International Regulations for Preventing Collisions at Sea, commonly known as COLREGs, which dictate that all vessels should act in a manner that prevents collisions, which includes altering course, slowing down, or stopping if necessary, to avoid a close-quarters situation.
