Two kinds of the ship-borne wave recorder for the actual ships were tested. Both recorders consist of the relative wave height meter and the vertical accelerometer. The relative wave height is measured by the different manner for each other, the one is radar and the other supersonic distance meter. The wave spectra measured by these encounter wave recorders were compared with those measured by the buoy wave recorders of various types as well as by the wave measuring tower and good agreement has been obtained provided the moderate wave height and the low forward speed of the ship which was the case of the comparative experiments. Model experiments on the encounter wave recorder at the bow of ship was also carried out and it has been shown that the encounter wave recorder at the bow is reliable to measure the waves with sufficient accuracy if the ship sails in beam seas. It is recommended that the encounter wave recorder at the bow is to be used in low and moderate beam seas while the wave recorder at the ship side is useful in the severe head seas.
