Many maritime accidents are due to poor weather conditions and several meters of sea waves & strong winds that make rescuing people in the sea very difficult. So even when the search & rescue boat reaches the danger zone to save people in distress they spend too much time out on the water. In deeper analysis, three different specific scenarios. As far as the beach scenario is concerned, both remote control and supporting lifesaver boat have already been developed. In this case, since the main cause of death is drowning, the device should also have an in-water camera since the problem is frequently lost time due to searching for the person who is already under water. In the open water case, the remote control boat should also be able to search for victims and locate them as fast as possible; to do that it should be interfaced with worldwide standardized systems for sea search, such as the Cospas-Sarsat system, which works with a GPS signal. Whether the victim is provided or not with a GPS transmitter, a camera should nevertheless be necessary to approach the victim in the last phases of the mission or to locate him/her when the distress signal is given by someone else. In this case, the existing alternatives are mainly focused on floating devices, able to reach the position of the person on aerial vehicles able to throw a floating device to the person or to correctly identify his/her position. During or after a flood there is the need to save as many people as possible but since weather conditions are usually very bad and places where people need to be rescued are often narrow and not easy to reach, on very few occasions is rescue by helicopter or boat feasible. Moreover, specialized flood rescue units are rare and often rescuers pay with their own lives for their improvisation. The remote control developed here will be optimized for an open sea environment both for civil and military rescue. After comparison, the final solution adopted was that of a catamaran, i.e. a double-hulled boat which should reach the correct location and rescue the victim by using a net. The advantages of this solution are: possibility to use the space between the two hulls to pick up the victim, stability in rough waters, the higher speed of catamarans, maneuverability and lightness compared to mono-hulls. The structure is composed of two fiberglass hulls joined together by an aluminum upper structure which ensures rigidity of the system. To increase stability in case of very severe sea conditions, hulls are equipped with tubular rubber. The rescue system is made of an aluminum rectangular frame, placed between the hulls, to which a net is bound on three sides. When the victim is reached, the netted frame is lowered into the water and then lifted with the victim.
