Human-powered watercrafts are marine vessels that are set in motion by human power, typically used recreational activities. The types of human-powered watercrafts include row boats, paddle boats, pedal boats, canoes, kayaks, surf skis, and rowing shells. Human-powered watercrafts date back to 8200 BCE. The 3 methods used to propel human-powered watercrafts are through the hands or feet, through the hands with oars, paddles or poles, or through the feet with pedals and crank or treadle. Classic examples of human-powered watercraft are canoes, rowboats, and paddle boats. Canoes can carry at least 1 seated or kneeled passenger that controls its movement through a paddle. A rowboat is propelled by oars that are attached to the boat at a pivot. A paddle boat, also known as a pedalo, is a boat propelled by a paddle wheel that is turned by pedals similar to a bicycle.
