The present invention is to prevent piracy by completely preventing pirates from boarding a vessel even if the pirates approach the vessel, wherein a triangular driving plate (12) is provided with a reciprocating movement means at the sides (20) or the stern of various kinds of vessels and moves via a clearance portion (17) of a casing (1) in the state that the triangular driving plate (12) is exposed upwards, such that the triangular driving plate (12) can forcedly separate various boarding means (20) which are hung on the side (20) of the vessel therefrom. Therefore, the triangular driving plate (12) can be quickly moved to remove hung hooks (30) off the vessel when pirates approach and throw the hooks (30) on the side of vessel to mount boarding means. |
