I got on the FCC site and I'm a little confused about the current marine radio licensing requirements for a charter boat captain. I operate a charter boat on the great lakes. One of the questions on the FCC form is if I'm required by law to have the marine radio aboard. I do not know whether I am required by law or not. Does anyone have the answer for this? Yes, I do have two marine radios aboard but am I required by law to have any?
