KEEPING A SAFE NAVIGATIONAL WATCH Flashcards
Collision regulations is split into 3 sections, what are they
A.S.R
- Conduct of vessels in any condition of visibility.
- Conduct of vessels in sight of one another.
- Conduct of vessels in restricted visibility.
Rule 5, state 3 ways in which you will achieve it in order to “make a full appraisal of the situation and of the risk of collision”
Look out
Sight
Hearing
All available means
Why should a “vessel 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.
What factors should all vessels take into account when determining a safe speed?
State of visibility.
Traffic density.
Maneuverability of the vessel.
At night the presence of background light.
The state of wind, sea and current, and the proximity of navigational hazards.
The draught in relation to the available depth of water
Under rule 8 action taken to avoid collision with another vessel shall result in what?
Shall be such as to result in passing at a safe distance
The effectiveness of the action shall be carefully checked until when
The other vessel is finally past and clear
When you’re a stand on vessel what is your actions
Crossing situation under rule 15, own vessel is stand on. As the stand on vessel under rule 17 keep course and speed.
Why is it important to use radar in sea stabilized mode for collision avoidance
If there is a current present the sea stabilized mode will more accurately show the heading of targets on the display and therefore aspect. This is important for applying the colregs which are mainly based on aspect.
What does rule 10 not relieve any vessel of
Her obligation under any other rule
A vessel using a tss shall
Proceed in the appropriate traffic lane in the general direction of traffic flow for that lane so far as practicable keep clear of a traffic separation line or separation zone normally join or leave a traffic lane at the termination of the lane
How shall a vessel cross a lane
On a heading as nearly as practicable at right angles to the general direction of the traffic flow
When can a vessel enter an inshore traffic zone
When she is a vessel of less than 20 meters in length.
If she is a sailing vessel
If she is engaged in fishing
When enroute to or from a port.
Offshore installation.
Pilot station.
When can a vessel enter a separation zone ( other than crossing vessel)
In cases of emergency to avoid immediate danger; to engage in fishing within a separation zone
What should a vessel not using a TSS do
Avoid it by as wide a margin as is practicable
What operations exempt a vessel from complying with rule 10 to the extent necessary for carrying it out?
A vessel restricted in her ability to maneuver when engaged in an operation for the maintenance of safety of navigation.
A vessel restricted in her ability to maneuver when engaged in an operation for the laying, servicing or picking up of a submarine cable
