COLREGS

Question 1

Application

Rule 1

Answer 1

COLREGS apply
* on the High Seas and
* Waterways that are connected and navigable by seagoing vessels

As local authorities are allowed to set own, local rules, these take precedence over the COLREGS

Question 2

Responsibility

Rule 2

Answer 2

a) good seamanship goes beyond these rules (ship/crew properly equipped and qualified; every voyage is planned and executed safely and responsibly.

b) in immediate danger: deviate from these rules as last resort

examples for a)
stores, certification, hull integrity, fuel

Question 3

Definition: vessel engaged in fishing

Rule 3 d)

Answer 3

a vessel that is actually resticted in its manoevrability due to its fishing gear

Question 4

NUC < = > VRAM

3 f, g

Answer 4

NUC: unable to manoevre as required by these rules => this is NOT a choice

VRAM: restricted in abilitye to manoevre due to the nature of her work => this is a choice

Question 5

Definition:
Safe Speed

Rule 6

Answer 5

Every vessel shall at all times proceed at a safe speed so it can take proper and effective action to avoid collision and be stopped within an appropriate distance

traffic density
manoevrability
wind, sea, current
UKC
dangers present

visibility

OOW + Master

Question 6

Narrow Channels:
implications

Rule 9

Answer 6

Whether narrow or not depends on ship relative to fairway/channel

If proceeding within a narrow channel: keep as far to starboard side as is safe/practicable

Vessels shall not cross À narrow channel, if crossing would impede passage of a vessel that can only safely navigate in the channel.

< 20 m, sailing, fishing => shall not impede PDVs

IF impeding => normal rules apply! but this doesn’t relieve of the obligation not to impede

Question 7

TSS
parts

Rule 10

Answer 7

• traffic lanes
• separation line or zone
• inshore traffic zone

Question 8

TSS rules

Answer 8

• no need to keep starboard
• join/leave at termination of lane <=> otherwise as small an angle as possible
• crossing at heading in right angle to general direction of traffic flow => normal rules apply!
• <20m, fishing, sailing => shall not impede PDVs => but IF impeding: normal rules apply! but this doesn’t relieve of obligation not to impede

Question 9

Responsibilities between vessels in sight
(hierarchy)

Rule 18

Answer 9

1. NUC / VRAM
2. Fishing
3. Sailing
4. PDV

Question 10

Conduct of vessels in restricted visibility

Rule 19

Answer 10

no standon vessels under R.19

Radar:
* fwd of beam: no course change to port (unless overtaking)
* abeam/abaft: no course change towards the other vsl

No Radar:
* reduce speed if fog signal heard forward of beam

Question 11

Restricted visibility:
definition/measures

Answer 11

• restricted visibility depends on ship type and sea area (rule of thumb: visible range of side lights)

Measures:
* sound signals
* navigation lights on
* reduce speed
* extra lookouts
* inform Master
* keep quite
* close watertight doors

(Master’s standing orders)

Question 12

Sound signals
Normal visibility

Answer 12

Question 13

Sound signals:
Restricted visibility

Answer 13

All: every 2 minutes

• .. all lame ducks

Question 14

Sound signals restricted visibility
Aground/anchored

Answer 14

Grundsitzer = Ankerlieger BUT 3 distinct bell strokes before/after 5 seconds continuous

Question 15

Overview lights
