A vessel wireless terminal comprises: a memory storing a unique number of vessel; an indication signal generation circuit generating an indication signal indicating any one among an entry and a departure; a wireless transceiver generating a control signal responding to a first wireless signal transmitted from a directional antenna; and a control circuit storing the generated indication signal in the memory, leading the unique number of vessel and the indication signal stored in the memory to respond to the control signal to transmit the unique number of vessel and the indication signal to the wireless transceiver. The wireless transceiver converts the unique number of vessel and the indication signal into a second wireless signal, and transmits the second wireless signal to the directional antenna.
