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

- 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
Describe how you must conduct your watch as an OOW when operating with a pilot on the bridge

What is meant by execution of passage plan
During the execution stage of passage planning, mariners implement the plan developed during the planning stage to safely navigate the vessel from the departure point to the destination. Here’s how the execution stage of passage planning is carried out:Preparation: Before departure, ensure that all necessary equipment and resources are on board and in working order. This includes navigational instruments, charts, publications, communication devices, safety equipment, and any other relevant items.Briefing: Conduct a pre-departure briefing with the crew to review the passage plan, including the planned route, navigational waypoints, safety procedures, emergency protocols, roles and responsibilities, and any other relevant information. Ensure that all crew members understand their duties and are aware of potential hazards along the route.Departure: Depart from the departure point according to the planned departure time and route. Monitor weather conditions, tidal information, and any other factors that may affect the passage.Navigation: During the passage, navigate the vessel according to the planned route and navigational waypoints. Use navigational instruments such as GPS, radar, depth sounders, and compasses to maintain course and track the vessel’s position accurately.Monitoring: Continuously monitor the vessel’s position, speed, heading, and surroundings to ensure that it remains on course and avoids potential hazards. Use electronic chart display systems (ECDIS) or paper charts to track progress and cross-reference with visual observations.Adjustments: Be prepared to make adjustments to the passage plan as needed based on changing conditions, such as weather, tides, currents, traffic, or unexpected hazards. Consider alternative routes or waypoints if necessary to maintain safety and efficiency.Communication: Maintain communication with other vessels, shore authorities, and relevant stakeholders as required. Report any significant changes, incidents, or emergencies promptly and follow established communication protocols.Watchkeeping: Implement appropriate watchkeeping procedures to ensure that there is always a vigilant lookout for potential hazards, other vessels, and navigational challenges. Rotate watchkeeping duties among crew members according to established schedules.Documentation: Keep accurate records of the passage, including log entries, position reports, weather observations, and any significant events or actions taken. Document any deviations from the planned route and the reasons for those deviations.Arrival: Safely navigate the vessel to the destination according to the planned arrival time and procedures. Prepare for arrival operations, such as docking, anchoring, or berthing, and follow established protocols for securing the vessel.By effectively executing the passage plan and adhering to established procedures, mariners can ensure the safe and successful completion of the voyage. Regular communication, vigilant navigation, and proactive decision-making are essential elements of the execution stage of passage planning.
8 sections of notices to mariners
- General info
- Navigational warnings
- Notices to mariners
- Local notices to mariners
- Hydrographic notes
- Meteorological notes
- Regulatory notices
- Safety messages
Describe APEM
- Appraisal
Appraisal of all relevant information. At this stage all publications should be advised such as:
Navigational charts
Chart catalogue
Sailing directions and Pilot books
Ocean passages
Admiralty list of radio stations
Admiralty list of lights and fog signals
Tide tables
Routing charts - Planning
Once all the information has been appraised we move on to panning. At this stage we have to prepare a plan which is detailed and simple to understand. It is good and standard practice to lay out a plan from berth to berth and to mark all no go areas
Navigational marks
Safety Depth contours
Military areas
TSS
Pilot calling stations
Leading lines
UKC
Parallel indexing
Tides and Current
Deviation/ variation
Could alteration points
As everything doesn’t always go to plan a contingency plan should also be put in place with information such as emergency ports we could stop at along the way.
A detailed risk assessment should also be made.
- Execution
Once the passage plan has been approved by the master the bridge team will execute the plan. All colregs should be followed and in addition fuel, water and food rations should be taken into account.
- Monitoring
Monitoring is checking the position of the vessel by all available means, to ensure it remains within safe distance from any hazardous areas. Plotting the ship’s position using more than one method is a good practice and those include e.g. GPS, visual bearings, radar range/bearings and astro-navigation.
At the end of a voyage, a de-briefing meeting is to be held to share experience and lessons learned from the conducted voyage. This information can be used in future passage planning.
