In order to improve the hatch covers of a container ship, the calculations on deck wetness are applied to predict the water leakage into a cargo hold. The results obtained by the calculations are as follows : 1) The quantity of water flow into a cargo hold under the heavy weather is small, even where the gaskets of a hatch cover are eliminated. 2) The short term probability of deck wetness is small. The flow into the forward cargo hold is less than 10m^3/h, under the sea conditions of significant wave height of 7〜10m. 3) The long term probability of deck wetness is also not so high. According to these results, the improvement of hatch covers, such as elimination of gaskets, will be successfully adopted.
