The U.S. Navy has been actively engaged in the development of hydrofoil ships and craft since the late 1940's. During this period, a number of controversial design issues have been addressed by analyses, model experiments, subsystems tests, and full-scale trials of several experimental prototypes. This paper examines some of the central technical issues in retrospect and sets forth conclusions derived from development efforts. Some of the issues discussed include: surface-piercing vs. submerged foils; canard vs. conventional strut-foil configurations; retractable vs. fixed foilsystems; flap vs. incidence control; analog vs. digital autopilots; platforming vs. wave contouring; flat vs. banked turning; waterjet vs. propeller propulsion; and material selection.
