Visual Communications FAQs
The Visual Communications Flashing Lights course is intended for mariners seeking an original deck license, a raise of grade on an existing license, or an STCW endorsement as an Officer in Charge of a Navigational Watch (OICNW) on vessels of 500 Gross Tonnage or more.
The primary focus of the Visual Communications (Flashing Lights) course is to achieve and demonstrate proficiency in visual signaling using Morse Code (via flashing light) and to gain working knowledge of the International Code of Signals (Pub. 102).
