One of the primary concerns for the navigators was the current when passing the narrow channels. Setting the time to pass channels and controlling their own vessels there was greatly effected by the current. The present paper reported on the effect of tidal currents upon small vessels passing narrow channels, on the basis of the questionnaire for coastwise vessels and the traffic surveys in the channels; Obatake-Seto under the bridge and Miyanokubo-Seto. Most navigators thought that it was best, the schedule permitting, to pass those channels on slack water without sighting so many fishing boats, etc. Actually, half number of the vessels proceeding through the channels passed away from there with the current. Most vessels kept to her starboard side of the channel, and in the case of the Obatake-Seto they showed a tendency to pass the center of the channel under the bridge, particularly on fair current
