It’s not easy to remember the details of the Colregs when you aren’t at sea every day, but sometimes there isn’t time to look up an obscure one in practice. Mnemonics can help. Here’s an example:
Question: ‘Which side do you pass a dredger – ball daymarks, or diamonds?’
Answer – ‘Great balls of fire!!! Fire is red, so diamonds must be green. I’ll go with green for safety.’
How many can you think up?
