Device for removably securing an oar ( ) to an edge of a boat, comprising an oarlock ( ) accommodating a coupling member secured to the shaft ( ) of the oar ( ); the oarlock ( ) comprises a base ( ) supporting, via a spindle ( ), a pivoting transverse arm ( ) which has a cylindrical housing ( ) opening into its front end ( ) and locking means which have, to the rear and along the axis of the orifice of the housing ( ), selectively a section provided with a hole ( ) of the same diameter as the housing and a section provided with a hole ( ) of a smaller diameter; a pivot ( ) secured radially to the shaft ( ) of the oar ( ) having the same diameter as the housing ( ) and hollowed by an annular groove ( ) of a diameter equal to the smaller diameter of the locking means.

A dump-valve device for a craft, characterized in that it comprises: a plug valve (,) movable approximately rectilinearly relative to a fixed seat (,) supported by a craft transom plate (,), drive means (,) mobile in rotation along a rotary stroke of limited angular amplitude and able to be activated from inside the craft, and coupling means (,) interposed between the valve (,) and the drive means (,) to convert the rotary stroke of limited angular amplitude of the drive means into a rectilinear stroke of limited linear amplitude of the valve.

An inflatable pneumatic enclosure 1 of constrained geometric shape, comprising two main walls 2, 3 held the one relative to the other, in the inflated state of the enclosure, in a pre-specified relative position by a multiplicity of flexible links 4 interposed between said walls 2, 3, an inflation valve 6 being fixed in one of said walls 2 for the inflation of the enclosure, characterised in that the valve 6 is of the embedded or semi-embedded type with a valve body 7 extending inside the enclosure 1 under said mounting wall 2 and in that a spacing body 8 extends between the valve body 7 and the opposite wall 3 of the enclosure and is fixed to these, said spacing body 8 being dimensioned so that the two aforementioned walls 2, 3 are held in a desired relative position in relation to that obtained by the surrounding flexible links.
