The BRS system provides the protection of the boat from sinking and fire, only by replacing the corresponding nozzle on the fire extinguisher. It is the most convenient way to protect the boat from sinking. The use of the BRS system provides the protection of the boat and objects on board, as the boat remains on the surface even incase of water ingress. Because of a very simple use, the system can be handled by every crew member. No additional training is required. Reading the instruction for use is enough. The energy for filling buoyancy bags comes from the enclosed fire extinguisher. The fire extinguisher is independent of external factors(engine on the boat, batteries, generators, human factor, etc.) and thus works under all conditions.
