Experiment on the Sea Regarding Distress and Search of Small Fishing Boat-I

Abstract

The authors have made an experiment on board the ship with the aim of obtaining data which can be utilized for the search of a small fishing boat in distress at sea, and the following results have been gained, 1) The floating material was drifted to the leeward from the point where the material had been brought by the current. Therefore it is basically important to measure the current speed at the sea of the disaster. 2) The drift speed of the small drifting material by wind and wave (Vs) tends to decrease as the wind speed (Vw) increase. The relationship between them was illustrated as Fig.15. 3) Regarding (2), when a drift material was found the distance between an observer and the material would be estimated by the drifting time and Fig.15.
