In this study, a marine navigation is proposed in order to solve problems including deviation from the route while a marine leisure ship is sailing, which gives a prior guide about expected route deviation at a real time through searching or makes it returned to the main routes from deviated areas when it is deviated from the navigated route. The proposed system is set with main routes and auxiliary ones. The latter provides the former with a prior guide about positions tended to be deviated while a ship is being sailed. Therefore, it has both of the functions to prevent route deviation in advance and to guide and make a ship returned to main routes from deviated ones by measuring the position of the ship until auxiliary routes and main ones are the same when the ship is deviated from the route.Also, the proposed system can increase convenience and safety of a marine leisure ship by reducing the time for the route search server to search the routes from the deviated positions to the destinations and to transmit the information about them.

This study aims to design a chief VDR(Voyage Data Recorder) system which is appropriate to small and medium sized vessels and also implement the data about marine communication devices, sensors, etc. to be stored or printed at the navigator when those data are connected to VDR through data communication between marine navigation and VDR which are based on serial communication or internet in order to prove efficiency of the marine navigator. Also, the design of VDR is intended to be small and light in order to expand to apply it to small and medium vessels, which enables to analyze causes of marine accidents precisely through its characteristic functions which are the same as those at "vehicle mounted black-box" (location of the car, image and voice storage) by which the same roles are played on land.
