Abstract

System (10) for controlling a vessel, which vessel is provided with: propulsion means (40) for propelling the vessel, directional means for determining the direction in which the vessel is propelled, which system is provided with: speed regulating means (32, 36) for influencing the propulsion supplied by the propulsion means, steering means (30, 34) for influencing the directional means, at least one or more navigational aids (28) which provide those who are operating the speed regulating means and/or the steering means with data relating to the navigation, in which the system is provided with means by which the data (14, 16, 22, 24) coming from the navigational aid (28) is used to determine areas where the vessel must not go, and in which the speed regulating means or the steering means or both are provided with limiters (32, 36) by means of which the operation of the abovementioned means is rendered difficult if such operation would lead to the vessel moving in the direction of the abovementioned areas.

7. A control system according to claim 6 wherein multiple time-sequenced future vessel positions are indicated in the display of the vessel surroundings.

8. A control system according to claim 6 wherein each waterborne vessel position is indicated by a ship symbol comprising a framework having lateral dimensions corresponding to the breadth of the ship account being taken of the panoramic perspective, while the position of the ship symbol in the display corresponds to the position of the bow of the ship in the surroundings displayed.

9. A control system according to claim 8 wherein the framework comprises two vertical line sections, the distance between the vertical line sections being related to the breadth of the ship.

10. A control system according to claim 9 wherein the top or the bottom or the top and the bottom of each of the vertical line sections connects or connect to a horizontal line section extending toward the other vertical line section in each case.

11. A control system according to claim 6 wherein the display comprises a bar indicating both the actual course of travel and a desired course of travel in suitable units.

12. A control system according to claim 6 wherein the display comprises icons to display alarm signals.

13. A control system according to claim 6 wherein the forbidden areas are displayed on the display screen in a color or colors differing from the color or colors of the remaining areas.

14. A control system according to claim 6 wherein the navigation data is selected from the group consisting of radio navigation data, data output by GPS, LORAN or a DECCA system, geographical position data, radar imaging data, electronic nautical chart data, infra red sensor data, laser sensor data and combinations of any two or more of the foregoing.

15. A control system for controlling a waterborne vessel, the waterborne vessel having:

a) a propulsion unit for propelling the waterborne vessel through the water; and

b) a directional device for determining a direction of travel of the waterborne vessel is propelled;
