A manual for yachtsmen, both beginners or students, and experienced. It contains the rules of radio communication at sea and detailed vocabulary for receiving and transmitting urgent and everyday messages, reading navigation charts and weather forecasts, negotiating in charter companies and in the offices of local maritime authorities, etc., as well as a large explanatory dictionary of basic yachting terms and visual aids. If you decide to sail on foreign seas, then without the skills of maritime English, at least elementary, you not only endanger yourself and your crew, but also risk being fined a decent amount.
