Sailing Path Optimization Analysis with Uncertain Sea Conditions along Upwind-downwind Triangle Course

How to select an optimal sailing route with uncertain sea state information is a key to win. In this paper, firstly the roles of sea environmental parameters for sailboat sailing are analyzed based on hydromechanics principles. And then two-dimension sailing environmental model is set up for upwinddownwind triangle course based on course setting requests. And then the optimal sailing route is planned based on leg division and heading decision fuzzy comprehensive evaluation. Finally, considering the standard of sea conditions required in yachting area, simulations and data analysis indicate the effect of uncertain sea conditions in yachting arena on racing path optimization. The results will guide athletes and instructors to train scientifically.
