Human-powered watercraft are watercraft propelled by human power. The three main methods of collecting human power are directly from the hands or feet, through the hands with oars, paddles, or poles, or through the feet with pedals and a crank or treadle. While most human-powered watercraft use buoyancy to maintain their position relative to the surface of the water, a few, such as human-powered hydrofoils and human-powered submarines, use hydrofoils, either alone or in addition to buoyancy. Oared craft Oars are held at one end, have a blade on the other end, and pivot in between in oarlocks. Oared craft include: Racing shell Using oars in pairs, with one hand on each oar, is two-oar sculling. The oars may also be called sculls. Two-oared sculled craft include: Adirondack guideboat Banks dory, Gloucester dory, and McKenzie River dory Dinghy Sampans rowed by foot in Ninh Bình Province of northern Vietnam. Scull, Single scull, Double scull, Quad scull, and Octuple scull Skiff Row boat Using oars individually, with both hands on a single oar, is sweep or sweep-oar rowing. In this case the rowers are usually paired so that there is an oar on each side of the boat. Sweep-oared craft include: Coxless pair, Coxed pair, Coxless four, Coxed four, and Eight Galley, Dromon, Trainera, and Trireme Moving a single stern-mounted oar from side to side, while changing the angle of the blade so as to generate forward thrust on both strokes, is single-oar sculling. Single-oar sculled craft include: Gondola Sampan Sandolo Paddlecraft Paddled watercraft, or paddlecraft, uses one or more handheld paddles, each with a widened blade on one or both ends, to push water and propel the watercraft.. Commonly seen paddlecrafts include: Canoe, Outrigger canoe, Umiak, Waka, Pirogue, Shikara, Dragon boat, and Dugout Kayak, Sea kayak, Flyak, and Baidarka Coracle Paddleboard Pedaled craft Pedals are attached to a crank and propelled in circles, or to a treadle and reciprocated, with the feet. The collected power is then transferred to the water with a paddle wheel, flippers, or to the air or water with a propeller. Pedaled craft include: Amphibious cycle Hydrocycle Pedal-powered kayak Pedal-powered submarine Pedal-powered hydrofoil Pedalo Poled craft A pole is held with both hands and used to push against the bottom. Poled craft include: Punt Raft Makoro Other types Other types of human-powered watercraft include: Float tube Hand-cranked submarine (disambiguation) Hand-operated cable ferry Paddleboarding Gallery See also
