A floating anchor (2) containing an airbag (3) placed in a rocket shaped plastic casing (1 ), is placed in a launching tube (5) at the bow of the speedboat facing the water, at an angle. When the speedboat takes a dangerous inclination, a gyroscopic mechanism (13) switches off the engine of the speedboat and detonates the charge (6) in the launching tube (5) and launches the rocket (1 ) in the water at an angle. The rocket (1 ) enters the water, unfold the connecting rope (4) and the moment this rope fully unfolded and stretched, it mechanically activates the airbag detonator (8). The airbag (3) expands, breaks the external casing of the rocket (1 ) and deploys the floating anchor (2) in the water. The boat slows down sharply and avoids capsizing and/or collision. The floating anchor (2) can be detached from the speedboat at the connecting point (22) when the releasing mechanism (21 ) receives an electric impulse from a button in the dashboard. This will detach the floating anchor (2) from the boat. In this case the floating anchor (2) sinks so as to avoid entanglement with incoming boats. Following some preset time, a water soluble mechanism (18) (fig.4&5) allows a can with pressurized air (23) to inflate a balloon (17) that brings the floating anchor (2) to the surface for collection, after the water soluble capsule (24) has been dissolved. |
