SAILING CRAFT

摘要

A sailing craft has a bouyant body (1) carrying at least one aerodynamic surface (2,9) disposed to provide stability and control, a hydrodynamic surface assembly (6) and an aerofoil (7) . Body (1) and hydrodynamic surface assembly (6) are connected by a rigid beam (3) such their running axes remain parallel irrespective of the orientation of the beam (3) with respect to the longitudinal axis of the body (1). The aerofoil (7) is supported by the beam (3) and has rotational freedom such that any significant force generated by the aerofoil (7) will pass below the centre of mass of the craft when in operation and ensure dynamic stability. In addition, the running attitude of the hydrodynamic surface assembly (6) is controlled by the aerodynamic surface (2,9).
