Four basic hydrofoil parameters were chosen as optimization parameters 1 loading, 2 aspect ratio, 3 liftdrag ratio and, 4 the root bending stress. Consideration is given to only the static flying condition where all the load is carried by the total plan-form i.e. there is no nacelle and all the root bending stress is carried by foil thickness. A method for calculating the lift and drag characteristics of subcavitating hydrofoils operating near the free-surface is discussed.
