Human-powered watercraft include prehistoric, historic and well-known traditional and sporting craft such as canoes, rowing boats and [[galley]]s. The term ''human-powered boat'' is often used for more modern craft using propellers and water wheels for propulsion. These can be more efficient than paddles or oars and especially allow the use of the leg muscles which are generally stronger than arm muscles, even for non-athletes. Competitive rowing boats use sliding seats to engage the legs for propulsion with an oar for this reason, but require considerable skill to use efficiently. In addition, there is little skill required for forward propulsion while looking forwards and craft such as [[pedalo]]s are popular at resorts.

=====Hydrofoils=====
Hydrofoils have less water resistance at the highest speeds attainable by humans and are thus usually faster than displacement boats on short courses. The world speed record on water was set 27 October 1991 by MIT professor Mark Drela who pedalled a [[human-powered hydrofoil]], "[[Decavitator]]", to {{cvt|9.53|m/s|km/h kn mi/h}} over a 100-meter course in [[Boston]], Massachusetts, US.

=====Submarines=====
In 1989, the first human-powered International Submarine Race (ISR) was held in Florida with 17 craft. Since then nine more races have been held. The races themselves have been moved from the waters of Florida to the  [[David Taylor Model Basin]] at the [[Carderock Division of the Naval Surface Warfare Center]] in Bethesda, Maryland, and are held biennially. At the 9th ISR in 2007 (in which 23 submarines participated) several new records were set: A single-person craft, [[Omer5]] achieved a record speed of {{cvt|8.035|kn|km/h|order=flip}} breaking the Omer team's previous record of {{cvt|7.19|kn|km/h|order=flip}} set by Omer 4 in 2004. Also Omer 6 snatched up a record for non-propeller driven craft with a speed of {{cvt|4.642|kn|km/h|order=flip}} .<ref>{{cite web |url=http://www.isrsubrace.org/ |title=International Submarine Races |publisher=Isrsubrace.org |access-date=2012-04-14 |archive-date=2012-05-04 |archive-url=https://web.archive.org/web/20120504145250/http://www.isrsubrace.org/ |url-status=usurped }}</ref>
