Use of tidal diamonds and tidal stream atlases for chartwork 12 Visual aids to navigation Lighthouses and beacons, light characteristics 13 Meteorology Sources of broadcast meteorological information


Knowledge of terms used in shipping forecasts, including the Beaufort scale, and their significance to small craft


Basic knowledge of highs, lows and fronts 14 Passage planning


Preparation of navigational plan for short coastal passages Meteorological considerations in planning short coastal passages Use of and visual confirmation of waypoints on passage Importance of confirmation of position by an independent source Keeping a navigational record


15 Navigation in restricted visibility Precautions to be taken in, and limitations imposed by, fog 16 Pilotage


Use of transits, leading lines and clearing lines IALA system of buoyage (Regions A & B) Use of sailing directions


Pilotage plans and harbour entry 17 Marine environment Responsibility for avoiding pollution and protecting the marine environment 1 B Total teaching time 40 hours (plus time for revision, homework and assessments) Assessments


There are two assessment papers which need to be completed - and successfully passed. The time allocation for each paper is 1.5 hours with additional time for marking and debriefing.


The assessments are:


General Assessment (1.5 hours) Covering safety equipment and procedures, buoyage, basic radio communications, vessel lights and shapes and the rules of the road.


Chartwork (1.5 hours)


Questions about position fixing, dead reckoning and estimated position, preparing course to steers and tidal heights.
