In this paper, field experiments are carried out to measure ship motions and waves simultaneously when a small ship enters into harbour under severe weather conditions in winter. Navigator is feeling that safety is in danger on operating the ship when the fore landscape is invisible. So, we develop a new safety index at small ship entering into harbour and it is possible to evaluate visibility or invisibility of the harbour entering facility by analyzing relation between ship motions and wave effects. In the calculation of ship motions, we must convert to coordinate of viewpoint by coordinate diversion. And besides we need to divert to the sea level distribution on track of entering ship from the wave height of wave recorder. As a result, the method of new safety index is expected to reduce a sense of danger by quantitative analysis in case of entering into harbour.
