A hydrofoil craft (10) has a hull (12) supported above a water surface by a foil (20) connected to the hull (12) by means of support arm (16). In accordance with one form of the invention, the support arm (16) enables the foil (20) to move up and down with respect to the hull (12) in concert with upgusts and downgusts of water surrounding the foil (20) so as to maintain the hull (12) at an approximately constant elevation. In accordance with another form of the invention, the support arm (161) is supported by the hull (110) for pivoting about a longitudinal axis (114) extending in substantially the fore and aft direction of the hull. When rolling forces act on the foil (160) the support arm can pivot about the axis from a vertical position in response to the rolling forces while enabling the hull (110) to remain substantially level.
