Techniques are disclosed for systems and methods to provide assisted and/or autonomous navigation for mobile structures. A docking assist system includes a logic device, one or more sensors, one or more actuators/controllers, and modules to interface with users, sensors, actuators, and/or other modules of a mobile structure. The logic device is adapted to receive docking assist parameters from a user interface and perimeter sensor data from a perimeter ranging system mounted to the mobile structure. The logic device determines docking assist control signals based on the docking assist parameters and perimeter sensor data. The logic device may then provide the docking assist control signals to a navigation control system. Control signals and/or other docking assist analysis and/or parameters may be displayed to a user and/or used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.
