Communication is vital when at sea and there are different ways of achieving this, one method is to use flags.
Vessels use the International Code of Signals to message other ships or to people on shore. Each flag represents a letter of the alphabet and can also be used to send a more complex message.
Can you represent your name in Nautical flags?
You could use paint, crayons or even pieces of material and maybe even make your own flag signalling system to use at home.
