A collapsible transom for an inflatable raft has a front section including two parallel front struts and a rear section including a floor portion and a collapsible support portion. The floor portion includes two parallel rear struts, and the two parallel front struts and two parallel rear struts are slidably connectable to each other by insertion into tubular end portions. The support portion is pivotally connected to the floor portion and movable between an expanded position with the support portion substantially parallel to and spaced away from the floor to a collapsed position with the support portion adjacent the floor.

A life vest stowage device (1) comprises a receptacle (2) for stowing a life vest (3). The receptacle (2) has an opening (4) through which the life vest (3) is inserted into and removed from the receptacle (2). A closure is provided, by which the opening (4) can be opened and closed. The closure comprises a tongue (5) on a first side of the opening (4). The tongue (5) is arranged such that it can be folded across the opening (4) to obstruct the opening (4). On a second side of the opening (4), opposite to the first side of the opening (4), there is provided a pocket (6). The pocket (6) is arranged so that the tongue (5) can be inserted into the pocket (6) when the tongue is folded to obstruct the opening (4). With the tongue (5) folded to obstruct the opening (4) and inserted in the pocket (6), first and second strips (7, 16) of a second material are aligned with one another and can be squeezed together so that the closure is substantially flat. This ensures that the tongue (5) is secured in the pocket (6) by a hook and loop fastener and allows a security seal (17) to be applied to the closure.

Provided is a bionic rescue robot fish, including a fish body skeleton, a fish head skeleton, a fishtail swing mechanism, a pectoral fin swing mechanism, a rescue mechanism and a buoyancy adjusting mechanism. The fish body skeleton is movably connected to the fish head skeleton. The fishtail swing mechanism, the pectoral fin swing mechanism, the rescue mechanism and the buoyancy adjusting mechanism are arranged on the fish head skeleton. Bionic fish skin is attached to surfaces of the fish body skeleton and the fish head skeleton in a sealing manner. The fishtail swing mechanism, the pectoral fin swing mechanism, the rescue mechanism and the buoyancy adjusting mechanism are each communicated with a control unit. The rescue mechanism can release a lifesaving airbag, and the buoyancy adjusting mechanism can change the volume of fish belly part.
