Collection: International Code of Signals

The international code of signals is a nautical publication from the NATIONAL GEOSPATIAL-INTELLIGENCE AGENCY (NGA). It includes a description as well as graphic depictions of the vocabulary and signals used in emergency situations at sea. These are especially useful if you are in international waters as language barriers could cause extra trouble during an emergency situation.

The international code of signals aids those in need of help either for their ship, crew, or passengers. When mariners need help, they must resort to these depictions for assistance. 

These communication signals are well known throughout the maritime community. A captain and the crew do not need to worry about loss of communication due to cultural or language barriers when using these codes correctly. The codes in this nautical book provide an opportunity for the captain and the crew to signal for help to nearby vessels.
