A "Crew Regatta" is a competitive rowing event where teams, known as crews, race against each other in boats. These events can take place on rivers, lakes, or coastal waters and often feature multiple races throughout the day. Each crew typically consists of rowers and a coxswain, who steers the boat and coordinates the team's efforts. Regattas can vary in distance and format, including head races and sprint races. They are popular at both amateur and professional levels, with many universities and clubs participating. Notable regattas include the Henley Royal Regatta and the Head of the Charles.
