A simplified estimation of the height and period of waves generated by a small boat was proposed in previous papers. The estimated height and period of waves were in good agreement with field results using a small boat. In addition, a new method called MUSIC (Multiple Signal Classification) was proposed to analyze the direction of ship waves. The distribution of the directional spectrum of ship waves as estimated by MUSIC presented a sharp monotone peak, and the estimated results were supported by field results using a small boat. The proposed estimation of ship waves by MUSIC was confirmed to be very effective. In present study, the direction of waves generated by a small boat was determined using MUSIC. In the previous study, the triangular array was fixed to a stand on the quay, and the measurement of the ship waves was limited to the sea area near the pier. In the current study, a triangular array was made by three buoys in order to analyze the waves created by a ship offshore. The analytical results derived by MUSIC were analyzed and were confirmed to be highly effective.
