The optimum speed for fishing boats was derived by taking into account costs of the fishing boat and the labor productivity of the fishermen.<BR>The subject of this study is primarily high speed coastal fishing boats, and the following assumptions are made, <BR>1. the horse power of high speed fishing boats is proportionally double its speed.<BR>2. the fishing operations are one-day trips.<BR>3. the crew consists of only the owner of the fishing boat.<BR>4. the landing value and operating time in the fishing area are constant.<BR>Based on the above assumptions the most economical speed, that is the speed for minimum operating costs, the lower the speed, the more economical is the operating cost. However, as the speed of the boat decreases, the time at sea is prolonged and the fishermen are forced to long working hours. Therefore, the optimum speed for labor productivity is the present high speed of coastal fishing boat, or ever higher.
