D Conduct of Vessels in Restricted Visibility

Question 1

BOTH INTERNATIONAL & INLAND You are operating a power-driven vessel in fog. Your vessel is proceeding at a safe speed when you hear a fog signal ahead of you. The Rules require you to navigate with caution and, if danger of collision exists ____________________.

Reference: Rule 19(e)

Answer 1

Reduce to bare steerageway

A vessel which hears apparently forward of her beam the fog signal of another vessel, or which cannot avoid a close-quarters situation with another vessel forward of her beam, shall reduce her speed to the minimum at which she can be kept on her course.

Question 2

BOTH INTERNATIONAL & INLAND: The steering and sailing rules for vessels in restricted visibility apply to vessels in sight of one another in fog. TRUE or FALSE?

Refer to COLREG 19(a)

Answer 2

False

This Rule applies to vessels not in sight of one another when navigating in or near an area of restricted visibility.

Question 3

BOTH INTERNATIONAL & INLAND: You hear the fog signal of another vessel forward of your beam. Risk of collision may exist. You MUST turn your engines off. TRUE or FALSE?

Refer to COLREG 19(e)

Answer 3

False

Except where it has been determined that a risk of collision does not exist, every vessel which hears apparently forward of her beam the fog signal of another shall reduce her speed to the minimum at which she can be kept on her course.

Question 4

BOTH INTERNATIONAL & INLAND: The steering and sailing rules for vessels in restricted visibility apply to vessels only if they are showing special purpose lights. TRUE or FALSE?

Refer to COLREG 19(a)

Answer 4

False

This Rule applies to vessels not in sight of one another when navigating in or near an area of restricted visibility.

Question 5

BOTH INTERNATIONAL & INLAND You are in charge of a vessel operating in restricted visibility and hear a fog signal forward of the beam. Nothing appears on your radar screen. You must _______________________.

Reference: Rule 19(e)

Answer 5

Slow to bare steerageway

Except where it has been determined that a risk of collision does not exist, every vessel which hears apparently forward of her beam the fog signal of another vessel, shall reduce her speed to the minimum at which she can be kept on her course.

Question 6

BOTH INTERNATIONAL & INLAND The steering and sailing rules (Rule 19) for vessels in restricted visibility apply to vessels _____________.

Reference: Rule 19(a)

Answer 6

Navigating in or near an area of restricted visibility

Question 7

BOTH INTERNATIONAL & INLAND: You hear the fog signal of another vessel forward of your beam. Risk of collision may exist. You MUST take all way off, if necessary. TRUE or FALSE?

Answer 7

TRUE

If a vessel hears forward of her beam the fog signal of another shall reduce her speed to the minimum at which she can be kept on her course. She shall if necessary, take all her way off.

Question 8

BOTH INTERNATIONAL & INLAND: You hear the fog signal of another vessel forward of your beam. Risk of collision may exist. You MUST begin a radar plot. TRUE or FALSE?

Refer to COLREG 19(e)

Answer 8

True

If a vessel hears forward of her beam the fog signal of another shall reduce her speed to the minimum at which she can be kept on her course. She shall if necessary, take all her way off.

Question 9

BOTH INTERNATIONAL & INLAND By radar alone, you detect a vessel ahead on a collision course, about 2 miles distant. Your radar plot shows this to be a meeting situation. You should _____________________.

Reference: Rule 19(d)(1)

Answer 9

Turn to starboard

Analteration of course to port for a vessel forward of the beam, other than for a vessel being overtaken shall be avoided.

Question 10

BOTH INTERNATIONAL & INLAND In restricted visibility you hear the fog signal of another vessel forward of your beam. Risk of collision may exist. You MUST __________________.

Reference: Rule 19(e)

Answer 10

Reduce her speed to the minimum at which she can be kept on her course if necessary

A vessel which hears apparently forward of her beam the fog signal of another vessel, or which cannot avoid a close-quarters situation with another vessel forward of her beam, shall reduce her speed to the minimum at which she can be kept on her course.

Question 11

BOTH INTERNATIONAL & INLAND You are underway operating in restricted visibility. You hear the fog signal of a vessel which is somewhere ahead of your vessel. You must _______________________.

Reference: Rule 19(d)

Answer 11

Slow to bare steerageway and navigate with caution

A vessel which detects by radar alone the presence of another vessel shall determine if a close-quarters situation is developing and/or risk of collision exists. If so, she shall take avoiding action in ample time.

Question 12

BOTH INTERNATIONAL & INLAND When operating in fog and other vessels are detected by radar you should maneuver in ample time if a close-quarters situation is developing. TRUE or FALSE

Reference: Rule 19(d)

Answer 12

True

A vessel which detects by radar alone the presence of another vessel shall determine if a close-quarters situation is developing and/or risk of collision exists. If so, she shall take avoiding action in ample time.

Question 13

BOTH INTERNATIONAL & INLAND While operating in restricted visibility, a vessel which detects by radar alone the presence of another vessel shall determine if a close quarters situation is developing or risk of collision exists. If so, she shall __________________.

Reference: Rule 19(d)(ii)

Answer 13

Avoid altering course toward a vessel abaft the beam

A vessel which detects by radar alone the presence of another vessel shall determine if risk of collision exists and so far as possible avoid an alteration of course towards a vessel abeam or abaft the beam.

Question 14

BOTH INTERNATIONAL & INLAND: The steering and sailing rules for vessels in restricted visibility apply to vessels only if they have operational radar. TRUE or FALSE?

Refer to COLREG 19(a)

Answer 14

False

This Rule applies to vessels not in sight of one another when navigating in or near an area of restricted visibility.

Question 15

BOTH INTERNATIONAL & INLAND A vessel hearing a fog signal forward of her beam has not determined if risk of collision exists. She is required by the Rules to reduce her speed to __________________________.

Reference: Rule 19(e)

Answer 15

Bare steerageway

A vessel which hears apparently forward of her beam the fog signal of another vessel, or which cannot avoid a close-quarters situation with another vessel forward of her beam, shall reduce her speed to the minimum at which she can be kept on her course.

Question 16

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

Reference: Rule 19(d)

Answer 16

Take avoiding action as soon as possible

A vessel which detects by radar alone the presence of another vessel shall determine if a close-quarters situation is developing and/or risk of collision exists. If so, she shall take avoiding action in ample time.

Question 17

BOTH INTERNATIONAL & INLAND: The steering and sailing rules for vessels in restricted visibility apply to vessels navigating in or near an area of restricted visibility. TRUE or FALSE?

Refer to COLREG 19(a)

Answer 17

True

This Rule applies to vessels not in sight of one another when navigating in or near an area of restricted visibility.
