A swimmer emergency alerting, tracking, rescue assistance, and rip current mapping system includes a stand and a life preserver that is removably mounted to the stand. The stand includes a solar panel or other charger, and the life preserver includes a battery receiving power from the charger and a sensor that is driven by the battery, such as to detect a location of the life preserver. The stand and the life preservers may wirelessly communicate with another device, such as a user device, to provide information on a status of the stand and the life preserver. A drone may fly from the stand and collect images of a shore, and the drone may process the images to identify a rip current. The drone may use data from a watercraft identifying rip current to train the processing of the images.

A wearable safety device for preventing drowning includes a housing for wearing on a user's wrist or limb and configured to be waterproof, biometric sensors, a motion sensor, a water detection subsystem, a processor for receiving input data from the biometric sensors, the motion sensor, and the water detection subsystem, and to evaluate whether the input data indicates a potential drowning or distress event based on predetermined threshold logic, a dye release mechanism for visibly marking surrounding water with a non-toxic dye upon activation by the processor, an alert subsystem communicably coupled, and a wireless communication module for transmitting a distress signal to a paired mobile device or networked system.

Rescue flotation systems for use in near-shore and offshore environments to assist with rescue of individuals in dangerous aquatic conditions are disclosed. The rescue flotation systems include a flotation body having a grabbable ring positioned around an outer perimeter, an internal storage compartment, an emergency call actuator configured to trigger a distress response upon activation by a person in distress, a location tracker, a communications system configured to transmit a wireless distress signal including the location to responders upon activation, a distress indicator configured to emit a local visual and/or audible distress signal upon activation, and a power supply (e.g., solar panel) configured to power the location tracker, the communications system, and the distress indicator. Some of the rescue flotation systems further include life-sustaining and first-aid supplies stored in the internal storage compartment.
