Q

R2b

A

Construing (interpreting) + complying
due regard (need to do) shall be had
> Dangers of NAV
> Collision
> Special circumstance
> limitations of vessels involved
AVOID IMMEDIATE DANGER

(b) In construing and complying with these Rules due regard shall be had to all dangers of navigation and collision and to any special circumstances including the limitations of the vessels involved which may make a departure from these Rules necessary to avoid immediate danger.

Q

Look Out

A

R5
At all times - sight, hearing, all available means
Appropriate to prevailing crcomstances and conditions
Make full appraisal of every situation = ID ROC

Every vessel shall at all times maintain a proper look-out by sight and hearing as by all available means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision.

Q

What is a Safe Speed

A

R6
Proper & effective action
Avoid collision
Stop at safe distance to
Prevailing crcomstances and conditions

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

Q

Safe Speed when fitted with Radar
Let’s Rub Snot In My Mask

A
  1. Characteristics, efficiency, limitations
  2. Range restraints
  3. Interference , proximity (sea,rain,close or on same brg)
  4. Small targets (wood, buoys, ice)
  5. Cluttered (number & movement)
  6. Radar used for range

Q

ROC

A

Shall use all available means appropriate to
Circumstances and conditions
Determine ROC

Long range scanning + plot for early detection
Assumptions on scanty info
In doubt act
Steady brg & decreaseing range = ROC
Close brg change may exist ( large/tow)

Q

Action to Avoid Collision
A, B, C, D, E

A

R8
A - Ample Time, Positive = Good Seamanship
Actions to avoid ROC as per R8,

B - Bold (Big Enough)(Change Aspect)
(Readily apparent visually & Radar)
(NO YAWING)

C - Course Alteration, most effective if
sea room allow (Early, substantial)
avoid Close Quarters Check Action for another

D - Pass at safe Distance, monitor until clear

E - Stop, slow, astern = More time

F - i) Not to impede take early action
ii) Not to impede in ROC shall take action
iii) Not to be impeded take action avoid ROC

i. Vsl<20m, Sailing, Fishing not to impede
j. RAM Maintenance in TSS exempt

Q

Pecking Order

A
  1. NUC
  2. RAM
    1. CbD
      1. Fishing
        1. Sailing
          1. Power-Driven
            1. Plane/WIG
              Only when in sight / as required by Rule 9, 10 or 13
18
Q

Restricted Visibility

A

a. Vsl’s not in sight (In or NEAR Restricted Visibility)
b. Safe speed adapted to prevailing conditions
c. Shall have engine ready
d. Rules 1 - 10 still apply
e. Detection by radar alone, ROC
Take action in ample time
Avoid
i) a/c to Port for vessel forward of beam
ii) a/c towards vessel abeam / abaft beam
f. Except if ROC does not exist
i) if hearing a Fog Signal forward of the beam
ii) Cannot avoid a close quarters situation
Shall reduce speed to minimum (bare steerageway)
Take all way off & navigate with extreme caution until Danger is clear

( Fog Signal Vsl > 200m = 2nm) (vsl < 75m = 1nm)

19
Q

Shapes

A

Circle / Triangle = 600 ,
Cylinder / Diamond Height = 1200

20
Q

Ranges of Lights

A

Length. MH. Side. Stern Tow. All Round (R,G,Y)
>50 6. 3. 3. 3. 3
12-50. 5. 2. 2. 2. 2
12-20. 3. 1. 2. 2. 2
<12. 2 1. 2. 2. 2

21
Q

Vertical Distances of Lights

A

If two mast head lights are carried
Aft 4.5m higher than forward

Lights should be seen as separate @ 1000m

Sidelights 3/4 of MH Height

Sidelights > 1m from MH

All Round 2m vertical spacing

Aft Anchor min 4.5m below forward

22
Q

When may the ordinary practice of a seamen be required and departure allowed?

A

If by following the rules it becomes dangerous to navigation or possible collision as result of special circumstances or limitations of vessels involved and if not using good judgement would endanger the ships involved, a deviation is permitted but only to avoid immediate danger
