The study deals with several problems about deck wetness on ocean-going ships. The deck wetness is one of the important performance factor of seaworthiness, and the trend of deck wetness has been investigated mainly in relation to loads on deck due to shipping of water, a change for the worse of ship stability, seakeeping quality etc. In those investigations, the deck wetness is generally used to mean the situation in which the relative motion amplitude between deck and wave surface would exceed the freeboard, therefore, it seems that the magnitude of the amplitude has been examined as a principal subject of study as usual. However, the time during which the amplitude remains above a level of freeboard must be also one of most important parameter affecting the trend of deck wetness. This paper proposes a practical method for estimating the time period related to deck wetness in ocean waves on the basis of both the ship motions theory and the statistics.
