Abstract : A parametric design study was conducted to determine the characteristics and performance of a family of high speed hydrofoil craft in the size range from 100 to 300 tons gross weight and in the speed range from 60 to 90 knots. The results are presented in tables and plots of characteristics, speed and range as a function of size, design speed and sea state. Sensitivity studies were conducted to determine the importance and influence of the assumed and calculated parameters on the craft characteristics and performance. The product of two lift drag ratio and the propulsion coefficient was the most important parameter effecting the performance and the one which could be calculated with the least precision.
