Q

What is a “vessel restricted in her ability to maneuver”?

A

Because of its work, it has restricted ability to follow these rules. E.g. nav markers, cables, pipelines, dredging, surveying, transferring persons or cargo, handling aircraft, mine clearing, difficult towing.

Q

What is “restricted visibility”?

A

Fog, mist, rain, etc. (even sandstorms) that restricts visibility.

25
Q

There is a risk of collision if…

A

the bearing to another vessel doesn’t change.

26
Q

If there is any doubt about the possibility of collision…

A

take proper action to avoid it.

27
Q

Rules 4-10 apply when?

A

In any condition of visibility. Follow these rules at all times.

28
Q

Rules 11-18 apply when?

A

When vessels are within sight of one another.

29
Q

Rule 19 applies when?

A

In restricted visibility.

30
Q

When does a vessel need a lookout?

A

At all times. “Lookout” applies to sight and hearing. The lookout must be able to see and hear potential danger at all times and in all conditions.

31
Q

What about vessel speed?

A

Vessels must operate at a safe speed at all times. Consider visibility, traffic, weather, draft, background lights, “back scatter” light. Also, radar limitations.

32
Q

What is fundamental to remember about vessel speed?

A

The vessel must be able to stop before incurring danger.

33
Q

There is a risk of collision if I…

A

…have any doubts about it.

34
Q

Can there be a risk of collision even if the bearing to another boat is changing?

A

Yes, if we are at close range.

35
Q

To check bearing vs. an approaching vessel…

A

…use radar or compass bearing. Note that radar information can be “scanty”.

36
Q

Course changes to avoid collision should be:

A

…made in ample time AND be big enough to be observed by the other vessel.

37
Q

To avoid a collision I can either…

A

…alter course (probably preferred) or take way off/reverse engines.

38
Q

If I am worried about collision, it’s OK to…

A

…slow down to give more time to assess the situation.

39
Q

When traveling along a narrow channel, do what?

A

Stay as close as possible to the starboard.

40
Q

What vessels should not impede others in a narrow channel?

A

Sailboats, boats less than 20m, vessel engaged in fishing, and a vessel crossing the channel.

41
Q

How is a narrow channel defined?

A

It’s subjective.

42
Q

What about anchoring in a narrow channel?

A

Nope.

43
Q

Signal to pass on the port side in a narrow channel?

A

_ _ . . and the response is _ . _ .

44
Q

Signal to pass on the starboard side in a narrow channel?

A

_ _ . and the response is _ . _ .

45
Q

Can fishing vessels fish in a narrow channel?

A

Yes, but they must move for any vessel.

46
Q

Signal when approaching a tight/blind corner in a narrow channel?

A

Long blast 4-6 seconds.

47
Q

Traffic separation scheme: normally do what?

A

Go with the flow and stay away from the divider.

48
Q

Traffic separation scheme: join how?

A

Preferable at the end, else at a narrow angle.

49
Q

If you must cross traffic lanes…

A

… do it at a right angle.

50
Q

Traffic separation scheme: using the inshore zone?

A

20m or less, sailboats, fishing boats, to some location like a port, or to avoid danger.

51
Q

Traffic separation scheme: when it is OK to use the separation zone?

A

Leaving or joining the scheme, fishing, to avoid danger.

52
Q

Anchoring in a traffic separation scheme?

A

Nope.

53
Q

Vessels that may not impede in a traffic separation scheme?

A

Sailboats, boats less than 20m, fishing.

54
Q

Traffic separation scheme: vessels exempt from the rules?

A

Vessels restricted in ability to maneuver working on navigation items, or laying submarine cable.

55
Q

What is the third sailing rule, other than S and L?

A

If wind is on port, and I see vessel to windward, give way if i can’t tell if he’s on port or starboard tack.

56
Q

What exceptions would apply to the three sailing rules?

A

One boat is in a narrow channel, or one boat is NUC or RAM or fishing, or an overtaking situation.

57
Q

Who has right-of-way in an overtaking situation?

A

The boat being overtaken has right of way.

58
Q

How is overtaking defined?

A

More than 22.5 degrees abaft, so I can only see the stern light, not either of the sidelights.

59
Q

The overtaking vessel must keep clear until it is…

“past and clear” of the other vessel.
