The disclosure relates to a marine searchlight system with wiretapping remote controllers including a main body assembly, a wiretapping box and two remote controllers. The main body assembly includes a control motherboard configured to control a lighting module and a driving module. The control motherboard includes a DC power module and a signal receiving module. The DC power module provides a DC power. The signal receiving module receives a control signal. The wiretapping box is electrically connected to the DC power module and the signal receiving module. The two remote controllers are electrically connected to the control motherboard through the wiretapping box. The DC power module provides the DC power to two remote controllers respectively. Each of the two remote controllers allows to transmit the control signal to the signal receiving module through the wiretapping box, so that the control motherboard can control the lighting module and the driving module.

A computer system has processing circuitry to control a force feedback unit to progressively increase a force feedback applied to the input device in response to a manual maneuvering of the input device towards a virtual stop position being defined in between an equilibrium position and a mechanical end position of the input device. The virtual stop position is a software-defined set point acting as an intermediate trigger for the input device. The force feedback is progressively increased until it reaches a maximum force feedback at the virtual stop position; and control the force feedback unit to reduce the force feedback applied to the input device at the virtual stop position in response to a force of a manual maneuvering of the input device exceeding the maximum force feedback value.

Systems and methods for controlling a remotely located very high frequency (VHF) radio are provided herein. A system includes a VHF radio comprising a communication interface, a processor, and a memory including computer program code (CPC). The CPC is configured to, when executed, cause the processor to receive and transmit data. The system further comprises a marine electronics device (MED) remotely located from and in data communication with the VHF radio. The MED comprises a display, a processor, and a memory comprising CPC. The CPC is configured to receive at least one operational setting of the VHF radio, and cause on the display presentation of the operational setting. The CPC is further configured to receive an input at the display to change the at least one operational setting and send a signal to the VHF radio to execute the change in the at least one operational setting.
