==Speed records==
In March 2009, two new sailing speed records were set by vehicles based on the proa concept, one on land, and one on the water.

On March 26, 2009, [[Simon McKeon]] and Tim Daddo set a new C-class speed sailing record of {{convert|50.08|kn|km/h}} over 500 meters in the ''Macquarie Innovation'', successor to their previous record holding ''[[Yellow Pages Endeavour]]'', with a peak speed of {{convert|54|kn|km/h}}.  The record was set in winds of 22 to {{convert|24|kn|km/h}}, and came close to taking the absolute speed record on water, currently held by ''[[Hydroptère]]''.  Conditions during the record-setting run were less than ideal for the ''Macquarie Innovation'', which is anticipated to have a top speed of {{convert|58|kn|km/h}} – {{convert|58|kn|mph}}.<ref>{{cite web |url=http://www.sail-world.com/USA/New-World-Speed-Record:-Macquarie-Innovation-breaks-50---hits-54-knots/55222 |title=New World Speed Record: Macquarie Innovation breaks 50 – hits 54 knots |publisher=Sail-World.com |date=28 March 2009 }}</ref>

On March 27, 2009, Richard Jenkins set a world wind-powered speed record, on land, of 126.1 miles  per hour (202.9&nbsp;km/h) in the Ecotricity ''[[Greenbird]]''.  This broke the previous record by 10 miles per hour (16&nbsp;km/h).  ''Greenbird'' is based on a one-way proa design, with a long, thin two-wheeled body with a third wheel to the lee acting as an ama. The aka, which is in the shape of a wing, provides a significant amount of downwards force at speed to counter the heeling force generated by the high-aspect wing sail.<ref>{{cite magazine |url=http://blog.wired.com/cars/2009/03/british-man-set.html |title=Freaky Speeder Rides the Wind to World Record |author=Tony Borroz |magazine=Wired |date=March 27, 2009}}</ref><ref>{{cite web |url=http://www.greenbird.co.uk/ |title=Greenbird official website}}</ref>
