To explore the drifting character of fishing boats without working motors and people in the water is the target of maritime search and rescue. For improving and evaluating their target drifting trajectory prediction model, researchers at the South China Sea Marine Engineering Investigation Center of the State Oceanic Administration carried out 2-3 trials in Guangdong coast waters: two times for fishing boats without working motors, and three times for dummy in the water on February 2011 and April 2011. These trials found that the dummy and fishing boats mostly drifted to the right of the downwind, and between the directions of current and downwind more than 80% of the total test times. By binary regression analysis on drift velocity (a dependent variable), current velocity and wind speed (as independent variables), we obtained the following results: current-induced drift parameter is approximately 1.0, wind-induced drift parameters are 0.019 for drifting people and 0.038 for drifting fishing boats.
