This paper presents a study focused on a newly developed procedure for wave spectrum estimation using wave-induced motion recordings from a ship. The particular procedure stands out from other existing, similar ship motion-based pro-cedures by its computational efficiency and - at the same time- providing accurate estimates of the on-site wave conditions. In the paper, the procedure is applied to full-scale experimental data obtained from dedicated sea trial runs. The results show favorable agreement with corresponding wave spectrum estimates by a directional wave buoy.
