Abstract : An analysis techniques was employed to study the control system designs for a 110-ton and 300-ton hydrofoil craft. It is felt, generally fulfill these requirements and, in conjunction with the nonlinear simulation, may be expected to yield an accurate indication of prototype performance for conditions not involving hull impact or foil broaching. The accurate simulation of these two phenomena add substantial complexity to the simulation and were not included in this study (total loss of lift with a broaching foil was simulated). A total of 610 simulation runs were made. In this first section, a list of symbols covering those used for both the longitudinal and lateral analyses are presented and a detailed description of the geometric configuration of both craft (110-ton and 300-ton) may also be found. Two studies were made longitudinal and lateral control system studies.
