1. A device for raising and lowering a boat anchor, the device comprising:

  • a winch for driving the boat anchor;

    a DC electric motor connected to the winch without a clutch release mechanism and operable to turn the winch in the anchor raising direction or the anchor lowering direction and powered from a DC power source supplying a DC supply voltage;

    an up control circuitry adapted to connect the DC power source to the DC electric motor in a polarity which turns the winch in the anchor raising direction;

    a down control circuitry adapted to connect the DC power source to the DC electric motor in a polarity which turns the winch in the anchor lowering direction;

    an up-down switch connected to the up control circuitry and the down control circuitry and configured to energize the up control circuitry and de-energize the down control circuitry in an up position of the up-down switch, and configured to energize the down control circuitry and de-energize the up control circuitry in a down position of the up-down switch;

    a boosting circuitry within the down control circuitry comprising a DC to DC boost converter which operates when energized to convert the DC supply voltage to a boosted DC voltage higher than the DC supply voltage;

    wherein when the up-down switch is in the up position, the up control circuitry supplies the DC supply voltage to the DC electric motor;

    wherein when the up-down switch is in the down position and the boosting circuitry is energized, the down control circuitry supplies the boosted DC voltage to the DC electric motor so as to provide an increased turning speed of the DC electric motor and thereby rapid lowering the anchor.
