A multi-functional aquatic vehicle comprises a main body. The main body comprises: a propulsion system, comprising at least one propeller for changing a motion attitude of the main body; a camera system, comprising at least one camera; a communication system, comprising a signal receiving module for receiving an external signal detected by the aquatic vehicle and a signal transmitting module for transmitting a signal to an external control system; and a control system, for controlling an operating state of the propulsion system, adjusting a capturing angle of the camera system and controlling internal and external communication of the communication system. A towing hook device comprises: a driving system, a connecting mechanism and a towing hook mechanism. The driving system drives the connecting mechanism to rotate such that the towing hook mechanism turns over or rotates to release a load.

A system and method for selecting alternate global positioning system coordinates is provided. The system generally comprises a geolocation device, processor operably connected to the geolocation device, and non-transitory computer-readable medium having instructions stored thereon. The instructions instruct the system to select alternate GPS coordinates based off geospatial data received by the processor as well as parameters of the system that may limit the alternate GPS coordinates in which the system may select. The parameters may be selected within a user interface of the system.
