This book was written at the request of the Ministry of Defence (Navy) and has been compiled and validated with the full support and cooperation of the Royal Navy both the School and the Department of Maritime Studies of the Plymouth College of Technology, and the Seafarers Education Service and College of the Sea.
The book is designed to teach seafarers the basic techniques of chartwork as a necessary preliminary to the practice of navigation.
