Abstract: Telemetry system for a ship propulsion system with a stationary part and a movable part that is movable relative to the stationary part. The telemetry system includes a processor, a data acquisition unit, at least one sensor, and a local power source. The processor, the at least one sensor and the power source are arranged in the movable part. The at least one sensor can measure an operational state of the movable part. The processor is connected to the at least one sensor for receiving signals from the at least one sensor and can transmit the received signals to the data acquisition unit. The local power source is arranged for providing power to at least one of the processor and at least one sensor, and the transmission of the received signals is arranged by a wireless communication link between the processor and the data acquisition unit.

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.
