Visit an authorized dealer that sells maritime devices nautical charts, vector charts & raster charts, maritime books, nautical instruments, Zulu flags, and more. Such companies provide goods and services that meet the ISO 9001 standards. 

There are various country flags, pennant flags, numerical flags, and signal flags needed for flag state compliance for vessels sailing. Here are some important flags and alarm signals that are mandatory for ships and vessels. 

  • Alpha flag - Diver below 
It is a flag with a blue and white color. The alpha flag indicates the warning signal when a vessel has a diver down the water.

  • Man overboard alarm

  • Zulu flag - I require a tug
