It is well known that a ship can be regarded as a type of wave recorder and, under the assumption of linear superposition, wave spectra can be estimated from the measured ship motions. Following the previous report, the authors discuss the capability of a method to estimate the directional wave spectra by use of nonlinear programming. In this report, 1) Effect of the difference of variance of waves in the tank on the estimated spectrum, 2) Effect of the speed of towing carriage on the estimated spectrum have been investigated. For this purpose, the measurements of the encounter waves on the towing carriage have been conducted in a relatively high speed condition at Marin Dynamics Basin of NRIFE (National Research Institute of Fisheries Engineering, Japan), in which several types of irregular waves have been generated by using different phase angle. By comparing the estimated directional wave spectra and the measured one, the capability of the method has been confirmed.
