| Practical Navigation for Officers of the Watch 2nd Edition - A Frost
The original Practical Navigation for Officers of the Watch replaced the title Practical Navigation for Second Mates. It extended the scope and brought in the principles and theory to cover the requirements of the International Convention on Standards of Training Certification and Watchkeeping for Seafarers related to the use of charts and other Admiralty navigational publications, chart constructions, visual and radar terrestrial navigation, and the use of celestial bodies for the calculation of compass errors and for position fixing.
This new second edition now includes modules on ECDIS, which has had such a fundamental effect on the practical application of the basic principles of chartwork-the sections on which have been retained in full. A module on ARPA has been included to enhance the section on radar navigation which forms such an important adjunct to the use of ECDIS. All navigational aspects of planning and executing the voyage safely are included with worked examples, exercises and answers with all necessary extracts from nautical publications.
The modules on celestial navigation have been retained as they are not only still relevant to existing training standards, but cover a topic in which it is becoming increasingly difficult to maintain competence due to the ease in which geographical position at sea is now available. |
