SYLLABUSES
PART L
GENERAL
I. The syllabuses for the various grades of certificate are set out in this Schedule.
2.
In each paper questions may be set combining one or more paragraphs.
3. The syllabus for a higher grade in both written and oral examination Includes the syllabus of that subject (if any) for certificates of lower grades,
SECOND MATE (FOREIGN-GOING).
4. A candidate should demonstrate his understanding of his work by means of sketches drawn with reasonable accuracy. Answers to problems in pracdcal navigation should, where appropriate, be accompanied by a figure drawn reason- ably to scale.
5. In the paper on practical navigation, total correction of altitudes by means of tables may be used. In the paper on "Principles of Navigation" cach correction must be shown separately.
6. The papers on "Principles of Navigation" and "Mathematics" are in- tended to test the candidate's grasp of fundamental technical ideas and processes required in his work at sea. Mathematical proofs of formulae are not required.
7. Paper 1. (written).
General Ship Knowledge. (3 hours).
(1) The names of the principal parts of a ship. General ideas on abịp coo- struction. The candidate will be expected to show his practical acquaintance with longitudinal and transverse framing, beams and beam knees, watertight bulkheads, batchways, rudders and steering gear, shell plating, double bottoms and bilges, stem frame, propeller and propeller shaft, stem tube, sounding piget. air pipes and general pumping arrangements. The stiffening and strengthening to resist panting and pounding. Cause and prevention of corrosion in a ship's
structure.
(2) The meaning of the terms Block Coolficient, Displacement and Dead weight. Use of Displacement and Tous per inch scales to determine weights of cargo, etc. from draughts, Effect of density of water on draught. Fresh water allowance. The laws of floating bodies. The meaning of the terms Buoyancy and Reserve Buoyancy General understanding of Centre of Gravity and Centre of Buoyancy and the effect of adding or removing weights. Metacentric height. The danger of slack ballast tanks,
(3) Rigging a ship for loading and discharging cargo and the use of derricks and winches. The stowage and dunnaging of cargoes including bulk cargot). Protection against damage by sweat. Bulk oil cargoes. Calculations of capaci ties taken up by part cargoes and of space remaining. Conversion of weigh! measurement of cargo into space measurement and vice versa. Elementary ideas on the making and use of cargo plan. Ventilation systems of holds and tanks. (4) The names and functions of various parts of a ship's lifeboat The types of construction. Capacity, buoyancy and number of persons. Care and maintenance of lifeboat equipment, lifebuoys, lifejackets, fine throwing appli- ances, fire appliances, lights and sound signals.
(1) Given the Variation and a table of Deviations to convert True Courses into Magnetic and Compass Courses and Vice Versa. To find the compass course and distance between two positions. The effect of current on speed. Allowance for leeway. Given compass course sicercd, the speed of the ship and the direction and rate of the current to find the true course made good. To find the course to steer allowing for a current
(22) To fix the ship's position on a chart by simultaneous cross bearings, bearing and range, or by wireless cross bearings applying the necessary correc- Loos. To fix the ship's position by bearings of one or more objects with the run between, allowing for a current and to find the distance at which the ship will pass a given point To fix the ship's position by horizontal sextant angles.
(3) The use of clearing marks and horizontal and vertical danger angles. (4) To find the time and height of high and low water at a Standard Port Admiralty Tide Tables). The use of tables or diagram to find the height of tide at any given time and thence the approximate correction to be applied to soundings or to charted heights of shore objects.
(3) Candidates will be examined orally on the information given on a chart or plan, particularly about buoys, lights, depths and nature of bottom, contour lings, tides and tidal streams. Recognition of the coast. The intelligent use of Sailing Directions. Chart correction.
9. Paper 3. (written).
Practical Navigation. (3 hours).
(1) Practical problems on Plane, Parallel, and Mercator Sailing.
(2) The use of the Traverse Tables to obtain the position of the ship at any time given compass course and errors and the run recorded by log or calculated by time and estimated speed, allowing for the effects of wind and current, if any. (3) To find the latitude by Meridian Altituds of the Sun or a Star. Latitude by an observation of Polaris,
(4) From an observation of the Sun or Star near the meridian to And the prition line and the latitude through which it passes in a given longitude.
(9) To determine the position line and a position through which it passes from an observation of the Sun or a Star out of the Meridian.
10 To find the ship's position at the time of the second observation by the e of position lines obtained from two different observations and thence the 400g position if required.
(7) To find the True Bearing of the Sun of a Star and the deviation of the compass for the direction of ship's head.
10. Paper 4. (written).
Mathematics, (2 hours),
( Algebra. Addition, Subtraction, Multiplication, Division, Law of Indices, Insertion and removal of brackets. Simple equations-problems. Do relopment of Formulao, transposition and evaluation. Simultaneous equations of the first order involving two unknowns-problems. Simple Factors, Fractions. The solution of the Quadratic Equation. Graphs. Axes of reference. Co- ordinates. Construction and reading of graphical diagrams, e.g. weather statistics and displacement curves. Problems on graphs. The ideas of ratio, proportion and variation and the application to simple problems.
Common Logarithms. The practical use of logarithms to base 10; their use in simple calculations involving multiplication, division, simple powers and
