摘要： Provided is a navigation assistance device capable of obtaining an obstacle zone by target in consideration of an allowance. A navigation assistance device for obtaining an obstacle zone by target from a relationship between an own ship and a target ship includes a margin acquisition unit that acquires a margin indicating the degree of allowance, and an arithmetic unit that obtains a margin position which is a position separated from at least any of the bow or stern of the target ship in a target occupied space set with reference to the position of the target ship by a distance determined according to the margin, obtains a collision course based on a position determined according to the motion vector of the target ship with reference to the margin position, and calculates the obstacle zone by target based on the obtained collision course.

摘要： A ship monitoring system makes it easier to grasp a heading of another ship, and includes a first data generating part, a second data generating part, and processing circuitry. The first data generating part generates first ship data indicative of a position and a velocity of a first ship. The second data generating part generates second ship data indicative of a position and a velocity of a second ship. The processing circuitry calculates a risk value indicative of a risk of the first ship and the second ship colliding each other, for each point on an estimated course of the second ship, based on the first ship data and the second ship data, when assuming that the first ship changes the course and reaches the point. The processing circuitry displays a risk area indicative of a heading of the second ship at the point where the risk value is more than a threshold.

摘要： A propulsion control system on a marine vessel includes at least one propulsion device configured to propel the marine vessel and at least one proximity sensor system configured to generate proximity measurements describing proximity of objects surrounding the marine vessel. A control system is configured to receive the proximity measurements, access a preset buffer distance surrounding the marine vessel, calculate a velocity limit for the marine vessel in one or more directions of the objects based on a difference between the proximity measurements and the preset buffer distance surrounding the marine vessel so as to progressively decrease the velocity limit as the marine vessel approaches the preset buffer distance from any of the objects, and control the at least one propulsion device such that a velocity of the marine vessel does not exceed the velocity limit in the direction of any of the objects.

摘要： A collision avoidance system and method for a watercraft for computing, visualizing, programming, and executing ship and hazard avoidance. The collision avoidance system and method employs a map visualization, a linear visualization, and a courses of action visualization to automatically provide a clear visualization of threats in real time in a manner which improves operator awareness for timely decision making and avoidance actions. In this regard, the collision avoidance system and method operate to reduce unwanted or unneeded information, ensure the visualization is task oriented as opposed to function oriented, ensure the visualization is intuitive, keep the key measures of the visualization consistent, and automate the searching of hazards across all charts and automate the closest point of approach in both distance and time of nearby tracks.

摘要： A server provides necessary data including at least map data and weather data for an ocean area to be navigated by a boat, and its AR-display data generating unit AR-displays a destination of the boat on captured forward-looking images displayed on a display of an information communication terminal at every via-target-point en route. And a server navigation data learning unit sequentially receives navigation data of the outboard motor from the terminal and learns navigation data that enables to reduce fuel consumption rate of an engine mounted on the outboard motor, and a server operation assist unit transmits the learned navigation data to the terminal so as to assist the operator's operation of the outboard motor accordingly.
