Open waters claim many victims. Lifeguards frequently have to fight in rough seas and strong currents to get to the drowning. The time slot to save a drowning is minimal. The way to the victim and back can cost valuable time, energy and even a human life. For this purpose we have developed a rescue board to speed up, simplify and modernize the process of rescue. The rescue board is operated by two electric motors via jet propulsion system. The batteries can be recharged on a solar powered docking station. After the duty, the boards can be placed and locked at the docking station.
