This information is for general knowledge only. It cannot be considered legal language. If you are writing official documents check your information and wording with the governing bodies of whatever project you are doing. I try to be accurate but nautical terms are notoriously changing. There are often many meanings depending on the era and place of usage, and I make mistakes.
