A hydrodynamic design procedure is presented, combining multi-objective sampling, metamodeling, and optimization. A design study of a flapped surface for a passenger hydrofoil is discussed. Hydrodynamics, stability and control are optimized with focus on maximum lift, minimum drag, and maneuverability/stability performance during take-off and turning maneu- vers. Shape optimization and control design are applied in combination with validated CFD simulations. Specifically, the hydrodynamic design of the foil sections is achieved though opti- mization, combining automatic shape/grid modification, adaptive sampling and metamodeling, and multi-objective optimization algorithms for maximum lift and minimum drag. A robust con- trol scheme is designed for the optimized shape. Flaps and rudders are commanded to stabilize roll and pitch motions, as well as steering the vessel during the desired maneuvers.
