This paper proposes an evaluation method for maneuverability of pleasure boats in order to develop an electronic control steering system of those boats. Based on usability as addressed by ISO9241-11, some evaluation criteria such as effectiveness and efficiency are defined for a task of obstacle avoidance and course return. For safety and repeatability, the simulation with a simplified ship simulator, which is composed a manual hydraulic steering system as hardware in HILS, is performed instead of experiments. As a result of the simulation to show design principle of the electronic control steering system, it is found that the usability of the manual hydraulic steering system deteriorates in the case of emergency avoidance. In particular, the wakes of the course return after the emergency avoidance are caused to be periodic by time delay in the dynamics of the pleasure boat. Therefore, it is found that the electronic control steering system of pleasure boats should have compensation for the time delay.
