Product Description


Welcome to the Marine Society’s Communications@Sea course.

Whether for routine or emergency purposes, the ability to communicate effectively with coast stations and other vessels is vitally important for the safe operation of vessels of all sizes and whether they are on the high seas or in inland waters.

This course has been based on the requirements of MSQ 20 (Communicate using equipment and visual means), with additional content from the Short Range Certificate and General Operator’s Certificate syllabi to cover all Sea Areas.

You can navigate through this course by using the arrow at the bottom of each page or via the navigation menu at the top of the page, if you want to jump to a specific section.
