Abstract: A marine autopilot system configured to control a marine vessel through a marine environment is disclosed herein. The marine autopilot system may obtain data of the marine environment from charts and community shared data and generate a path from a first location to a destination location in the marine environment. The marine autopilot system may control the marine vessel along the path based on the marine vessel dynamics and weather and water current conditions. Sensors may detect hazards on and in the water and object detections systems may classify the hazards. The marine autopilot system may control the marine vessel to avoid the hazards based on the location and classification of the hazards. Furthermore, sensors may be utilized to generate detailed 3D maps that change with time to dock the marine vessel at known and unknown locations.
