Abstract
Parametric studies are described of the influence of hull form, foil system, and pitch-heave control on hydrofoil hullborne seaworthiness. It is shown that foil systems have a significant and beneficial effect on head sea dynamics, and also that hullborne seakeeping differences between fully submerged and surface-piercing hydrofoil ships are insignificant providing bow foil load fraction is greater for the fully submerged ship, as is normally the case. The benefits of large bow foils and high deadrise angle are clearly identified, and a preliminary freeboard criterion for hydrofoil ships of 300 to 500 tons is derived.
