Recently, in the assessment of damage of a linkage type earthquake expected to generate from now on, we are anxious about information isolation arising in SETO-Inland-Sea with many islands. On the other hand, at the time of the disaster of an island in the past, the vessel and the operation ship (liner) have been utilized as a way stage of conveyance of stricken area support service and relief goods. The liner is used for transportation methods on the island every day.In this research, we proposed a wireless LAN system using liners. By using this system we will be able to prevent information isolation of the island in a disaster. We did the experiments of some wireless communications on the ad-hoc network constructed in SETO-Inland Sea, and evaluations were shown. Then, we also investigated and discussed shelters of the island to use as the base station, and evaluated by visualizing on GIS.
