SEAKEEPING CHARACTERISTICS OF FOUR MEMBERS OF HYDROFOIL HULL SERIES 65

A systematic study of the effects of hull-hydrofoil arrangement, hull length-beam ratio, sea state, loading, speed, longitudinal center of gravity location and simulated hydrofoil damping was made on the rough-water performance of a series of hull forms suitable for hydrofoil craft operation. Measurements of resistance, heave and pitch motions, and impact accelerations at two locations serve as a basis for comparison. From the particular range of parameters investigated it appears that: hulls appropriate to an airplane hydrofoil arrangement have better seakeeping characteristics than those intended for a canard layout; added resistance is shown to be a linear function of load, sea-state and speed; impact loads increase with length-beam and the square of the speed and decrease with hull loading; motions are reduced at high length-beam ratio and are insensitive to load; the response of hydrofoil hulls is confirmed to be non-linear.
