In order to provide verification that the proposed design of an amphibious hydrofoil lighter will meet its hydrodynamic performance specifications, a series of tests were carried out using scaled models of the vehicle and its components. It was shown that the proposed simple control system is effective in providing control in head and following seas. Tandem hydrofoil tests were carried out to verify design lift characteristics and, in particular, the choice of foil spacing was shown to yield optimum lift-drag characteristics at take-off. The model was operated in the foil borne mode with light ship and design load conditions, in calm water, head seas and following seas, using the proposed automatic height control. Directional stability and turning characteristics were analyzed.
