Abstract:

An experimental investigation of the heaving and pitching motions of a fully-ventilated, surface piercing dihedral hydrofoil craft was performed to ascertain the validity of applying linear superposition techniques. Tests were carried out in regular waves to obtain the response operators of the craft. The pitching and heav ing motions were then measured in long-crested irregular seas and analyzed using spectral techniques. It was found that the motion spectra in irregular seas could be predicted with rea sonable accuracy using the regular wave response operators with the wave spectrum of the sea. Author
