Hi, Could someone help me please in defining the duties of the following personnel. I have looked around the internet but a lot of it refers to the US Navy and am not sure if the exact same applies to the Royal Navy. Just a brief overview of each term will suffice! I have ideas on what the duties include and assume they are not all too different from the US Navy but I want to be sure! The terms are: Duty Officer Duty Senior Rate Quartermaster Boatswain's Mate Thank you!
