PURPOSE: A vessel data transmission system, a method, and a recording medium are provided to construct an efficient communication network between vessels, thereby reducing satellite communication expenses. CONSTITUTION: A land communication unit(130) includes one or more communication devices. One or more communication devices wirelessly communicate with land. A very high frequency(VHF) communication unit(140) communicates with a surrounding vessel by using a VHF transmitting/receiving device. A communication control unit(160) confirms whether or not a communication device communicates with the land.
