More specifically, detection unit 22 detects at least one of water temperature, tide, wave height, wind speed, tide, and salinity in the area where own consort ship 152 is located, based on environmental information, for example. If it is determined that one satisfies a predetermined condition regarding the environment, it may be determined that the environmental information satisfies the transmission condition. In this case, the detection unit 22 transmits consort ship information including the environmental information to the voyage information device 101 via the communication unit 20 . The predetermined environmental condition is, for example, that the water temperature is equal to or lower than a threshold, and is arbitrarily set by the user.

(Example 2)
The consort ship information device 121 may be configured to transmit the consort ship information to the voyage information device 101 when receiving a transmission request for the consort ship information transmitted from the voyage information device 101 .

For example, the communication unit 10 in the voyage information device 101 periodically or irregularly transmits a transmission request for consort ship information to the consort ship information device 121 . Upon receiving the transmission request transmitted from the voyage information device 101 , the communication unit 20 in the consort ship information device 121 transmits the latest consort ship information held by the detection unit 22 to the voyage information device 101 .

Further, the voyage information device 101 may be equipped with an AIS (Automatic Identification System) and may be configured to acquire the position information of the consort ship 152 regularly or irregularly. In this case, the detector 12 of the voyage information device 101 , for example, when determining that the acquired position information of the consort ship 152 satisfies the transmission conditions, transmits a request for transmission of the consort ship information to the consort ship information device 121 via the communication unit 10 . . The case where the position information of the consort ship 152 satisfies the transmission conditions is, for example, the case where the current position of the consort ship 152 is included in a predetermined area, or the case where the track of the consort ship 152 indicates a circling.

Note that the communication unit 20 in the consort ship information device 121 regularly or irregularly transmits the latest consort ship information held by the detection unit 22 to the voyage information device 101 regardless of the reception of the transmission request from the voyage information device 101.
