The paper presents a method to get better maneuverability by improving steering feelings so that inexperienced captains can smoothly control pleasure boats in critical situation for collision avoidance. To achieve this aim, firstly in order to show how much difficult it can be to control the boats; the complicated dynamics of them are evaluated by using a developed simulator including a steering system with simulation software. Then, it is considered to vary whole rotation angles and to give a virtual reaction torque on a helm. The results show that it may be able to navigate stably and reduce the meanders if the reaction torque is appropriately supplied and the whole rotation angle on the helm is suitably determined for inexperienced captains.
