Our Story

Hello! Welcome to the Marathon Mermaid! Having a Marathon Florida Boat Tour company has been a dream of John and Angela’s for years, and now is finally a reality! John, born and raised in Marathon, and Angela, a “transplant” from California, met in 2015, when Angela was a scuba instructor at the marina where John owned his rental boat business. Angela had dreamed of owning her own charter boat for years since she became a professional scuba diver and John wanted to be the person to make that dream come true with his skills and knowledge of boats. Skip forward a few years and they started to work on this dream, and that is where the “Marathon Mermaid” was born. Together, John and Angela put both of their ideas together to create this beautiful and unique vessel for some of the best Florida Keys boat tours and cruises in the area.
