The intention in doing this was to provide a text for candidates preparing for the chartwork and practical navigation of the Department of Trade Class V and Class IV certificates. Worked examples of all problems and calculations encountered in these papers together with ample exercises for self examination, are included, and specimen papers similar to Class V 'Chartwork and Practical Navigation', Class IV 'Chartwork', and Class IV 'Practical Navigation' are provided. All practical navigation problems and tidal calculations used may be worked with the extracts from the Nautical Almanac, and the extracts from the Admiralty Tide Tables included. Chartwork exercises however, inevitably require the use of a chart. Such exercises have been set on Admiralty charts 1179, 5050 or 5051, as these particular charts are published as inexpensive instructional charts, which, although not suitable for navigation, are full size and authentic and entirely adequate for practice purposes.

I think the quality should be changed to OCR with errors. Also it appears some pages are missing. Because as per amazon listing , there should be 292 pages. I have found another version online which has 305 pages , Might be good to check that too - https://www.pdfdrive.com/practi...s-e33692296.html
