In steering of a ship, the communications among crewmember is important for the safety steerage of the ship. The navigator selects the information, and makes decision. The officers and other members repeat the order to the navigator. In this study, the communication at the normal ship compare with the communication at the joystick-control system (advanced) ship. We recorded and analyzed all orders of the navigator and other crewmembers at the steerage bridge during arrival at the port and during departure from the port. We analyzed the two ships. The advanced ship has joystick-control system, was 1, 498 ton, passenger 400 persons and crew 8 persons. The normal ship was 6, 356 ton, passenger 400 persons and crew 14 persons. The numbers of communications between the navigator and another crew at the joystick-control system (advanced) ship were less than the numbers of communications at the normal ship. The joystick-control system (advanced) ship often contact another ships. When crew could not contact another ship (pleasure boat, fishing boat, etc.), the numbers of communications between the navigator and another crew in the high-speed ship increased sharply. It is important to construct the system, which can back up the navigator.
