A wing, buoyant in water has an upper wing surface comprising a deck upon which a rider stands, and, the wing is in water. A foot constraint proximate the wing leading edge and fixedly attaching the wing projects outwardly from the deck to release-ably receive the rider's forward foot. With the rider standing with both feet upon the deck, and the rider's forward foot ensconced within the foot constraint, and with the rider's aft foot proximate a trailing edge of the wing, the rider bodily heaves and pitches the wing to obtain a chordwise forward velocity thru the water. The forward foot constraint enables the rider to upheave the wing. A second foot constraint may attach the deck proximate the wing trailing edge. Another foot constraining system is comprised as a frictional device broadly applying the deck, and, may be used in addition to or in lieu of other constraints.
