A waterman or waterwoman is a person who participates in multiple water sports. Historically the term referred to those who make their living from the water such as professional fishermen or Lifeguard, but it has evolved to describe those who take part in a variety of water activities.
Wave riding sports include swimming, surfing, kayaking, and bodysurfing. In surfing terminology, "waterman" refers to a versatile athlete who can engage in various forms of water sports depending on conditions. One early person given this title was Duke Kahanamoku.
