The Brayfoil assumes a true single wing lifting section on both sides of symmetrical without joints or hinges, further exceeding the lift characteristics while reducing design complexity.
The wing sail auto-sets into apparent wind, making tacking a thing of the past. The wing rotates 360 degrees enabling unprecedented maneuverability, and ease of use. Steering and thrust level selection via two button/pulleys which morph the wing sail thickness.
The speed potential is in line with Americas Cup wing sails but much simpler and safer. Retractable wing sail for safe docking, can morph to near zero drag in storm conditions.
From small dinghy to large yachts, applications are endless, and may even play a valuable role in maritime drones (no motor needed).
SIMILAR TO THE AMERICAS CUP SAILS, BUT only to the extent that both wings reverse their camber by control.
The Americas cup wing sail achieves this by hinging two symmetrical wing sections and the folding of these panels only approximates a single sinusoidal lifting wing section.
The Brayfoil also automatically sets an appropriate angle of attack as opposed to the Americas Cup wing sail, that requires a crew to manage this aspect.
