Human-powered watercraft
Résumé
Human-powered watercraft are watercraft propelled only by human power, instead of being propelled by wind power (via one or more sails) or an engine.
The three main methods of exerting human power are:
directly from the hands or feet, sometimes aided by swimfins;
through hand-operated oars, paddles, or poles, or;
through the feet with pedalss, crankset 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.
Rowing
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
Paddling
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
Pedals are attached to a crank and propelled in circles, or to a treadle and reciprocated, with the feet.
