The method includes using vessel speed feedback control to adjust operational characteristics of the engine so as to achieve the setpoint vessel speed. The method also includes determining a measured vessel speed and filtering the measured vessel speed. In response to determining that the measured vessel speed is within a given range of the constant setpoint vessel speed, the method includes transitioning to the cruise control mode and comparing the filtered measured vessel speed to the constant setpoint vessel speed for purposes of the feedback control.
