Many navigation support systems are put to practical use. But when manoeuvering in port, captain oneself manoeuvers the ship. So it is important to know the physiological and mental intensity of captain in port for safty manoeuvering. The authors measured heart rate (HR) of a captain of T. S. Shioji maru manoeuvering in port for about one year. The HR was changed to relative one, represented as %HR. %HR is measured by the following equation : %HR=(HRex-HRrest)/(HRmax-HRrest)×100 given : HRex means HR during various activities. HRrest stands for the lowest HR while sleeping. HRmax indicates the predicted maximum HR due to age. The results are as follows. (1) %HR on each stand-by patterns are obtained. (2) Relation between %HR and experience in each port is partly obtained. (3) The factors that raised %HR are partly obtained. And some improvements are shown. (4) %HR shows the mental intensity of captain manoeuvering in port.
