So, go buy one. They are nice to communicate with crew who are away on a dinghy or ashore, or if you are away. just remember when you talk on the VHF, everyone within ear shot can hear your conversation. I remember a guy on his radio telling another boater that he had a fancy for a woman who worked on one of the nearby light houses. He went on and on about his passion and I got on line and reminded him she probably was listening to him as well. He never gave that a thought before I told him. End of communication LOL. And, like the radio in your boat, you have to use the same protocols.
