Seamanship Flashcards
(30 cards)
List five occasions in which you would be expected to call the master of the ship.
On board ship emergencies
Navigational Uncertainties
Weather Changes
Navigation Equipment Failure.
Any points laid out in the masters standing orders.
Part B of the Collision Regulations is split up into three sections, what are they?
- Section I Conduct of vessels in any condition of visibility
- Section II Conduct of vessels in sight of one another
- Section III Conduct of vessels in restricted visibilit
What is rule 5 about?
State three ways in which you will achieve it in order to “make a full appraisal of the situation and of the risk of collision”
Keeping a lookout. By
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?
- The state of visibility
- The traffic density including concentrations of fishing vessels or any other vessels
- The manoeuvrability 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
What factors additionally should vessels with operational radar take into account?
- The characteristics and limitations of the radar equipment
- Any constraints imposed by the radar range scale in use.
- The effect sea state or weather will have on radar detection.
- The possibility that small vessels, ice and other floating objects may not be detected by
- Radar range selection and its limitation
- The number, location and movement of vessels detected by radar
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 course or speed correction shall be carefully checked until when?
The other vessel is finally past and clear
What does Rule 10 not relieve any vessel of?
Her obligation under any other rule
A vessel using a traffic separation scheme shall
Proceed in the appropriate traffic lane, in the general direction of traffic flow.
So far, as practicable, keep clear of a traffic separation line or separation zone.
Join or leave a traffic lane at the termination of the lane.
How shall a vessel cross a Traffic separation lane?
On a heading as nearly as practicable at right angles to the general direction of traffic flow
When can a vessel enter an Inshore Traffic Zone?
- When she is a vessel of less than 20 metres in length
- If she is a sailing vessel
- If she is engaged in fishing
- When en route to or from a port,
- Offshore Installation
- Pilot Station
- To avoid immediate danger
When can a vessel enter a separation zone (other than a 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 the widest margin as it 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 manoeuvre when engaged in an operation for the maintenance of safety of navigation
- A vessel restricted in her ability to manoeuvre when engaged in an operation for the laying, servicing or picking up of a submarine cable
Except where rules 9, 10 and 13 otherwise require, a power-driven vessel shall keep out of the way of
Give 4 examples
- A vessel not under command;
- A vessel restricted in her ability to manoeuvre;
- A vessel engaged in fishing;
- A sailing vessel
In rule 19, what actions should be taken upon encountering restricted visibility?
Proceed at a safe speed
Notify the master
Sound appropriate sound signals
Turn on Navigation lights
Have engines ready for immediate manoeuvre
If a vessel detects by radar alone the presence of another vessel and a close quarters situation is
developing she must take avoiding action.
What should be avoided as far as possible if she alters course?
An alteration of course to port for a vessel forward of the beam, other
than for a vessel being overtaken
an alteration of course towards a vessel abeam or abaft the beam
List 6 things that the OOW should do on encountering restricted visibility
- Call the master
Turn Navigation lights on. - Start fog signal
- Post additional lookouts
- Check gain & tuning on Radar
- Have engines ready for manoeuvre
- Make an entry in the log book
List 6 reasons for calling the Master to the bridge
- On encountering restricted visibility
- Not sighting land/navigational marks when expecting to
- Sighting land/navigational mark that you don’t expect
- Difficulty in maintaining course due to weather etc
- Traffic situation requires master’s attention
- Master has requested a call in standing orders
List 8 Admiralty publications that can be used for Appraisal when passage planning
- Chart catalogue
- Navigation charts
- Sailing directions/Pilot books
- List of Radio Signals
- List of Lights and Fog signals
- Tide Tables
- Ocean passages for the world
- Routeing charts
State 10 items of information useful for planning that can be found in the admiralty publications
- VTS stations to call
- Radio information required in report
- Requirements for pilots
- Details of navigation lights
- Height of tide for port entry
- Recommended routes
- Radar conspicuous objects for position fixing
- Predominant wind for ocean crossing
- Port facilities
- Location of Pilot boarding station
Explain what the following chart symbol mean and how that affects fixing the vessel’s position
- Steep coast, Cliffs
- Good for position fixing, radar ranges should give accurate fixes. for PI lines
Explain what the following chart symbol mean and how that affects fixing the vessel’s position
- Drying heights and contours above chart datum
- Not good for fixing
- Radar response is poor and echo depends on height of tide, will not give an accurate fix
- Not suitable for PI lines
