Officer of the Watch Oral Examination OOW for Yachts less than 3000gt

Introduction[edit | edit source]

Objectives of this Wikibook[edit | edit source]

The United Kingdom Maritime and Coastguard Agency (MCA) officer of the watch exam is not an easy exam and often frighten the students. The student will be expected to have a thorough knowledge on a lot of different subjects that we will try to reference here. This book is based on the syllabus the examiner will follow during the examination and which is defined in the MSN 1802 (M).

Extracts from the officials documents[edit | edit source]

From the MSN 1802 (M) : Certificates of Competency: Yacht Deck Officers Training and Certification Guidance

This Merchant Shipping Notice (MSN 1802) is part of a series, which gives guidance regarding the application of the Merchant Shipping Regulations. This Regulations implement in the United Kingdom the requirements of the International Convention on Standards of Training, Certification and Watchkeeping 1978, (STCW) and its associated code (STCW Code). Masters and deck officers serving in all UK-registered yachts and sail training vessels of 24 metres and over in loadline length and under 3000gt must be qualified in accordance with the Regulations or the LY2.

Given the nature of the yacht industry, the MCA has invoked these equivalency arrangements for Yacht restricted qualifications under the Merchant Shipping (Vessels in Commercial Use for Sport or Pleasure), for use in UK registered large yachts operating under the LY2. Privately owned yachts as described in the Summary on Page 1 may also apply the manning scales and qualifications as given under the LY2 as an alternative to the full requirements of the Regulations.

This notice details a route for certification restricted to yachts that is structured to provide a progressive career path for those in the professional yachting industry. Candidates meeting the requirements will be issued with a STCW certificate of competency (CoC) limited to service in yachts and sail training vessels. Oral examination

The out-line syllabuses for the Yacht Deck Officer MCA oral examinations are annexed to the MSN 1802(M) and are available from the MCA website. All references to oral examinations in this notice mean those conducted by MCA examiners to the MCA syllabus.

Since higher level training relies on the underpinning knowledge of the lower level training, it is expected that a candidate will have obtained the previous qualification prior to commencing training for the next higher qualification. Candidates should be aware that questions in the oral examination may, in addition to the published oral syllabus, include topics that should have been covered in previous training. It is generally expected that all training modules and short courses will be completed before attempting the oral examination, as these provide the knowledge on which the examination is based.

Oral examination passes for each level of certification are valid for three years. The oral examination pass must be in date at the time of issue of the CoC.

Navigation[edit | edit source]

Plan and conduct a passage including position determination[edit | edit source]

Key points[edit | edit source]

The passage plan ensures that the bridge management team is fully aware of the vessel intended voyage and of the contingency plans. The plan is from berth to berth and any changes to the intended voyage must be amended in the plan. The master is overall responsible for the plan but may delegate the task of creating it. The plan is consigned into a passage plan book and always available on the bridge.

The 4 stages of a passage planning are:

  • Appraisal
  • Planning
  • Execution
  • Monitoring

Appraisal[edit | edit source]

From consulting all relevant publications, all the potential dangers on the voyage are clearly identified. After considering existing routeing schemes, environmental factors reporting systems and vessels traffic services a clear indication of a safe route can be obtained.

The passage planning shall take into consideration:

  • The condition and state of the vessel.
  • Any special characteristics of the cargo.
  • The provision of a competent and well-rested crew.
  • Requirements for up-to-date certificates.
  • Appropriate scale, accurate and up-to-date charts and publications.

Planning[edit | edit source]

Tracks can be laid on the chart from berth to berth indicating the predetermined margins of error. Danger areas are marked on the charts, as are points, which could be useful for navigation. In the event of an emergency, contingency plans are also considered. The plan is approved by the master prior to sailing and must be kept on board of the vessel for 12 months.

The detailed voyage or passage plan should include the following factors:

  • The plotting of the intended route or track of the voyage or passage on appropriate scale charts.
  • The main elements to ensure safety of life at sea (Safe speed, speed and course alterations, clearance under the keel, contingency plans)
  • The details of the voyage or passage plan should be clearly marked and recorded.

Each voyage or passage plan as well as the details of the plan, should be approved by the ship’s master prior to the commencement of the voyage or passage.

Execution[edit | edit source]

Once the departure time is known, the estimated time of arrival at the destination can be found. ETA's at critical points in the plan can also be determined. Time of high water and clearer identification can be gained of the conditions the vessel is likely to face the throughout the voyage. Factors which should be taken into account when executing the plan, or deciding on any departure therefrom include:

  • The reliability and condition of the vessel's navigational equipment;
  • Estimated times of arrival at critical points for tide heights and flow;
  • Meteorological conditions, (particularly in areas known to be affected by frequent periods of low visibility) as well as weather routeing information;
  • Daytime versus night-time passing of danger points, and any effect this may have on position fixing accuracy;
  • Traffic conditions, especially at navigational focal points.

Monitoring[edit | edit source]

The vessel progress is continually checked against the planned route. Any necessary deviations are amended in the plan and the bridge management team advised. The navigational equipment is monitored and checked on passage and prior departure. The plan should be available at all times on the bridge to allow officers of the navigational watch immediate access and reference to the details of the plan.

Position determination[edit | edit source]

Magnetic variation[edit | edit source]

Magnetic variation is the difference between True Bearings and Magnetic Bearings and is caused by the different locations of the Geographic North Pole and the Magnetic North Pole plus any local anomalies such as iron deposits. Variation is the same for all compasses in the same location. Variation is based on geographical and time. The term Magnetic declination is a synonym but magnetic variation is more used in navigation.

Magnetic Deviation[edit | edit source]

Magnetic Deviation is the difference between Magnetic Bearings and Compass Bearings. Deviation varies for every compass in the same location and depends on such factors as the magnetic field of the boat, wrist-watches, etc. The value will also vary depending on the orientation of the boat. Magnets and/ or iron masses can be used to correct for deviation so that a particular compass will accurately give Magnetic Bearings.

TVMDC[edit | edit source]
Heading Example Mnemonic
True 212° True
Variation -5° E Virgin
Magnetic 207° Makes
Deviation +2° W Dull
Compass 209° Companion

To make the conversion between the compass heading to the true heading, variation and declination must be added or subtract. From True to Compass correction, West should be added, East should be subtracted.

Dead reckoning (DR)[edit | edit source]

Dead reckoning is simply a prediction of a future position based upon a course steered and a speed from a known present position. The DR position is only an approximate position because it does not allow for the effect of leeway, current or compass errors.

Estimated position (EP)[edit | edit source]

An estimated position is a DR taking into account the amount of predicted tidal stream, current or the effect of the leeway.

Course to steer (CTS)[edit | edit source]

A course to steer is predicted course in order to reach a destination taking into account the speed of the vessel, the predicted tidal stream, current or the effect of the leeway.

Running Fixe[edit | edit source]

A running fixe is a method of fixing the position when only one know fixing point is available, the time, head- ing any leeway and the speed of the vessel through the water.

Chart symbology[edit | edit source]
Transits or Leading lines[edit | edit source]

Transits or leading lines are natural and visual bearings that allow a safe navigation by sight and/or compass.

Clearing marks[edit | edit source]

Clearing marks are bearing draw on charts that allow a safe monitoring of navigational hazards. (Not More Than, Not Less Than)

IALA system of maritime buoyage A and B[edit | edit source]

The IALA system is predicting six kinds of signs which it is possible to take in all sorts combinations. Side signs are different in 'A Region' and 'B Region', however five remained kinds of signs are shared for both of regions.

Lateral buoys and marks are being put in harmony with accepted direction for marking the right and left page of fairway. In 'A Region' a green colour is obeying into the day and at night for marking the right side of the fairway, and for the left hand the colour red.

IALA System A[edit | edit source]

Cardinal marks

  • N quadrant: A White,Very Quick or Quick continuous
  • E quadrant: A White,Very Quick 3 every 5 sec or Quick 3 every 10 sec
  • S quadrant: A White,Very Quick 6 + 1 long every 10 sec or Quick 6 + 1 long every every 15 sec
  • W quadrant : A White,Very Quick 9 every 10 sec or Quick 9 every 15 sec

Isolated dangers
Marks indicating Isolated dangers are being put directly above small obstacles which water is navigable around. They have the columned, bar or free shape different but not colliding with lateral buoys. They have the black colour with horizontal red belts. Two black spheres placed vertically are a highest sign. The light characteristic is White flash group Fl(2)

Safe water marks
A safe water mark is normally placed as the outer marker to a conventional buoyage system. It shows safe water all-round If there is an installed lighting it has the white colour and his rhythm can be: • Long Isophase • Long Occulting The letter Morse 'A' : Long Flash at 10 s intervals

Special Buoys and Marks
Special Buoys and Marks aren't making the navigational help. Pointing the special area or the object out is setting them which are informing maps or different right documents and nautical publications of. Additional characters are being painted yellow, they have the highest sign in the shape of lying cross (X) painted on yellow. Light if is installed, is also of yellow colour. Since a possibility of mistaking the yellow colour exists during the weak visibility with white, yellow lights of additional characters cannot have the rhythm adopted for white lights.

New Danger Buoy
The new buoys will be blue and yellow vertical stripes with an alternating blue and yellow occulting light. The shape is a pillar or a spar buoy, the size dependent upon the situation. The colour is between 4 and 8 vertical blue and yellow stripes, these stripes will be of New wreck buoy.equal width. The abbreviation of the colour will be BuY. Light is an alternating blue and yellow flashing light, the blue and yellow 1 second flashes are alternated with an interval of 0.5 seconds. Bu1.0s+0.5s+Y1.0s+0.5s= 3.0s

IALA System B[edit | edit source]

Only the colours of lateral and preferred channel markers are inverted from system A (a Port lateral marker is now green, instead of red). The shapes and light sequences remain the same.
