Abstract
Adding to the estimating system for one dimensional spectrum, estimating system for directional wave spectrum on board is developed measuring the time history of motions or acceleration of a running ship. Calculation of directional wave spectrum is made by adopting the so called Maximum Likelihood Method and by using a micro computer on board. There is a difficulty in transforming encounter frequency to absolute frequency, but here, we introduced a practical settlement for this problem.
