This is the award commemorative paper of “Weather Routing for a Fishing Vessel on the Route between Fishing Port and Fish Ground” printed in 2018. We have researched and developed the high-resolution weather routing system for fishing vessels since 2014. Weather routing is one of the methods to find minimum time route or minimum fuel consumption route by using weather information. We renewed the weather routing system of merchant ships for fishing vessels by applying a detailed grid size of weather information and a short interval of calculation. In this paper, we introduce the possibility to apply the weather routing to an actual fishing vessel, a skipjack pole and line fishing vessel and present that weather routing can influence safe navigation, energy efficiency and fishing trip planning in helping to decide a departure time for fishing grounds.
