Introduction
The course then describes the nautical publications and how to gather important information required during sailing, especially terrestrial coordinates features. Examine how a navigator used the nautical chart to plot courses and review daily works. Nautical charts are essential for marine navigation, the use of the title block, datum, and soundings. Study the difference between the two latitudes and learn how to measure the meridional parts of a given latitude. We Summarise the natural scale and use it to determine the relationship between a given distance on the chart and the earth. Recognize the symbols and abbreviations that can be used on charts and consciously avoid charted dangers during passage planning. Deduce how you can group the symbols and abbreviations under the required headings. You will learn about the features of the notice to mariners, light list, tide and current tables, and the coast pilots.
