In the paper "Use of Simulator in Assessment, Learning and Teaching of Mariners", the "safe navigation" is recognized as the balance between the mariner's competency and "navigation environmental difficulty". The "nine elemental technique for safe navigation" was developed for assessing the mariners' competency. The "technique of positioning" is defined as "the technique to find the position of own ship by selecting and recognizing proper objects by visual observation, radar, etc to understand her position and motion". At the present time, it is difficult to assess the concrete level of "navigation environmental difficulty". However, it is estimated that the behaviors of experienced mariners in bridge team indicate the required level of behavior to deal with "navigational environment". And analyzing experienced mariners' behavior could be estimated to bring us the required level with concrete values. Therefore, firstly in my research, that analysis on the "technique of positioning" was carried out. From this viewpoint, we have dealt with the behavior level shown by experienced navigators as the required level. The following chapters express the analysis of the relation between the navigation environmental difficulty and one of the most important techniques - "technique of positioning".
