A route planning device is provided with a display configured to display a chart on a screen, an operation interface configured to specify a position on the screen, a storage configured to store navigation publication related to a book referred to during past route planning in association with the position, a waypoint setting module configured to set a waypoint on the chart in response to a user's operation received by the operation interface, a navigation publication acquisition module configured to acquire navigation publication within a range of the set waypoint as a reference from the storage, and a display control module configured to display the acquired navigation publication on the screen of the display.

A traveling route generating device is provided, which may include a user interface and processing circuitry. The user interface may receive a home route that is a route on which a ship travels upon departing from a home harbor or upon returning to the home harbor, the home harbor being a location from which the ship departs. The processing circuitry may generate a traveling route between one of a destination of the ship and a current location of the ship, and a location on the home route.

A vessel control system for a marine vessel propelled by at least one propulsion device includes a wireless lanyard system including at least one fob worn by an individual on the marine vessel and a helm transceiver at a helm area of the marine vessel configured to receive radio signals from the at least one fob. A controller is configured to detect, based on communications between each of the at least one fob and the helm transceiver, that each of the at least one fob is present on the marine vessel. A missing fob is detected if at least one of the fobs is no longer detected at the helm transceiver, and then a man overboard event is generated. The vessel control system is configured to automatically activate one or more search assistance functions based on the man overboard event.

A marine vessel including a steering mechanism that includes a steering wheel including shift switches to cause the marine vessel to shift to a course holding mode to hold a course of the marine vessel, and a traveling direction maintaining mode to maintain a traveling direction of the marine vessel.

A method includes receiving a position hold signal from a human-machine interface of a marine vessel; in response to receiving the position hold signal, monitoring sensor data from at least one sensor; determining a hold position based at least on the monitored sensor data; and selectively controlling a thruster system of the marine vessel to hold the marine vessel in the hold position using the monitored sensor data.

A ship speed control device is provided, which includes a calculator and a throttle command value setter. The calculator calculates a throttle calculation value based on a difference between an actual ship speed and a target ship speed. The throttle command value setter sets, when the actual ship speed is below a first threshold determined based on a given throttle upper limit and the throttle calculation value is at or above the throttle upper limit, a throttle command value to the throttle upper limit.
