Study of the relation between VHF and Rules of the Roads
In recent years, the utilization of Automatic Identification System (AIS) and very high frequency (VHF) is recognized as being effective for preventing collisions at sea. Although VHF communication is useful for seagoing navigation, research on the relation between VHF and Rules of the Roads in Japan is relatively scarce. This study considers the relation between VHF and Rules of the Roads through the analysis of collision case data. This results of this study showed clear VHF-communicated agreements which can lead to an easy departure from Rules of the Roads dangerous, and VHF must be used diligently and in careful agreement with the collision avoidance action. One of VHF communication's main strong points lies in its importance as a tool that informs mariners of other vessels in the vicinity. This study concludes that the use of VHF by mariners should not take avoidance action against Rules of the Roads.
