Question 11

Define “Vessel engaged in fishing”

Answer 11

“any vessel fishing with any fishing apparatus which restrict manoeuvrability. (nets, lines, trawls)”

does NOT include a vessel fishing with fishing apparatus which don’t restrict manoeuvrability. (trolling lines)

Question 12

Define “Vessel Not Under Command”

Answer 12

a vessel through some EXCEPTIONAL circumstances is unable to manoeuvre as required and therefore unable to keep out of the way.

Question 13

Define “vessel restricted in her ability to manoeuvre”

Answer 13

a vessel from the nature of her work
includes but not limited to:
-laying, servicing or picking up a navigation mark, submarine cable or pipeline.
-replenishment or transferring persons, provisions or cargo. while underway.
-launching or recovering aircraft.
-mine clearance ops.
-towing which severely restricts her ability to deviate from their course.

Question 14

Define “vessel constrained by her draught”

Answer 14

POWER DRIVEN vessel, due to her draught in relation to the available DEPTH and WIDTH of navigable water, is severely restricted in her ability to deviate from her course.

Question 15

Define “restricted visibility”

Answer 15

ANY condition in which visibility is restricted.
-Fog
-Mist
-Falling snow
-Heavy Rainstorms
-Sandstorms
-Other

Question 16

Define “underway”

Answer 16

a vessel NOT:
- at anchor
- made fast to the shore
- aground

Question 17

Rule 5 - Look out

Answer 17

Every vessel shall at all times maintain a proper lookout by sight and hearing as well as all available means appropriate to the prevailing circumstances and conditions

so as to make a full appraisal of the situation and of the risk of collision.

Question 18

Rule 6 - Safe Speed

Answer 18

Every vessel shall at all times proceed at a safe speed so she can take proper and effective action to avoid collision and be stopped within a distance appropriate to the prevailing circumstances and conditions.

Factors determining safe speed for all vessels:
V D Makes Little Willies Drip.

and

by vessels with operational radar: Charlie Carr Eats Pie No More.

Question 19

Rule 8 - Action to avoid collision

Answer 19

Should be:
- positive
- made in ample time
- with due regard to good seamanship.

Question 20

Rule 7 - Risk of Collision

Answer 20

“I will take a regular series of compass bearings of the approaching vessel to determine if risk of collision exists.
If the compass bearing does not appreciably change, then risk of collision is deemed to exist.”

-If in doubt, assume risk of collision exists.

-Proper use of radar equipment:
>long range scanning for early warning
>radar plotting for systematic observation of detected objects.

-Do not make assumptions based on scanty information, especially radar.

-Be aware a risk of collision may still exist even with an appreciable compass bearing change for:
>large vessels
> a tow
> vessels at close range.

Question 21

Define “Not Impede”

Answer 21

take
EARLY ACTION
to allow
SUFFICIENT SEA-ROOM
for the
SAFE PASSAGE
of the
OTHER VESSEL

Question 24

Explain the overtaking rule

Answer 24

Rule 13
-Overtaking is the highest priority rule
-Vessel is considered to be overtaking is she is more than 22.5 degrees abaft the beam
-At Night: A white stern light = YOU ARE OVERTAKING
- Overtaking vessel must stay out of the way until finally past and clear and cannot later turn to port and turn it into a crossing situation.

Question 25

Define a “Head On” Situation

Answer 25

Rule 14
-Two Power driven vessels
-At Night: a mast headlight and / or both sidelights

Question 26

Define Overtaking

Answer 26

Vessel is more than 22.5 abaft the beam.

Question 27

Rule 12

Answer 27

Sailing Vessels
Starboard tack - Stand on
Port Tack - Give way

Leeward vessel - Stand on
Windward vessel - Give way

Question 28

Define Crossing Situation

Answer 28

Between 2 power driven vessels
Vessel on starboard side has right of way

Question 29

Action by give way vessel

Answer 29

Rule 16 :
“Every vessel which is directed to keep out of the way of another vessel shall,
so far as possible,
take early and substantial action to keep well clear. “
