Section II - CONDUCT OF VESSELS IN SIGHT OF ONE ANOTHER

Question 1

Rule 11

Answer 1

APPLICATION
Rules in this section apply to all vessels in sight of one another

Question 2

Rule 12

Answer 2

SAILING VESSELS
SV - Vessel with wind on port side gives way, if wind on same side, windward vessel gives way.

Windward side = opposite side that the main is carried on, or for square rigged vessel - opposite to the largest fore - aft sail.

Question 3

Rule 13

Answer 3

OVERTAKING
A) Any vessel overtaking any other shall keep out of the way of the vessel being over taken.

B) Over taking vessel = more than 22.5* abaft the beam. At night only the stern light would be visible not her side lights.

C) If any doubt assume that you are the overtaking vessel.

D) Overtaking vessel remains as such until finally past and clear, regardless of any bearing change.

Question 4

Rule 14

Answer 4

HEAD - ON SITUATION

A) When two PDV approaching head on, they must both take action by altering course to starboard and passing port to port

B) Situation exists when a vessel sees the other ahead so that at night would see mastheads in a line or both side lights, thus by day is the corresponding aspect.

C) If any doubt as to the situation exists, assume that it does. Act accordingly

Question 5

Rule 15

Answer 5

CROSSING SITUATION

When two PDV are crossing so as to involve ROC the vessel that has the other on her own starboard side is to keep out of the way.

Question 6

Rule 16

Answer 6

ACTION BY GIVE WAY VESSEL

(Vessel to keep out of the way). Shall as far as possible take early and substantial action to keep well clear

Question 7

Rule 17

Answer 7

ACTION BY STAND ON VESSEL

A) shall maintain course and speed. However may take action when it becomes apparent that the give way vessel isn’t taking action.

B) When the stand on vessel finds her self so close that collision can’t be avoided by the give way vessel alone, she shall take action that will best aid to avoid collision.

C) The stand on vessel shall, so far as possible, avoid turning to port for a vessel fwd of her beam in a crossing situation..

D) This rule does not relieve the give way vessel of her obligation.

Question 8

Rule 18

Answer 8

RESPONSIBILITY BETWEEN VESSELS

Except where rules 9, 10 , and 13 otherwise require -

Rule 13 - overtaking vessels shall always keep out of the way so the hierarchy of vessels does not apply. rules 9 and 10 direct specific vessels to do specific things.

Question 9

Rule 18

Answer 9

RESPONSIBILITIES BETWEEN VESSELS

• WIG craft in flight
• Sea plane taking off / landing
• PDV (includes WIG on the water
  and air cushion)
• SV
• FV
• RAM
• NUC

Question 10

Rule 19

Answer 10

CONDUCT OF VESSELS IN RESRTICTED VISIBILITY

A) Applies to all vessels in sight of one another in or near areas of restricted visibility.

S) every vessel shall proceed at safe speed adapted to the prevailing conditions

P) PDV shall have her engines ready for immediate manoeuvre.

D) Due regard shall be had to the conditions when complying with the rules of this section.

R) RADAR alone - determine if ROC exists - if yes, Avoid turning to port for a vessel forward of the beam, or towards a vessel abaft the beam.

R) Except where ROC doesn’t exist - Fog signal fwd of beam or cannot avoid close quarters - Shall reduce speed to min at which can be kept on course - if necessary take all way off - in any event navigate with extreme caution until danger of collision is over.
