Described are submersible assemblies including a support structure comprising a pair of flotation devices and a cabin pivotally coupled to the support structure between the pair of flotation devices having an outer enclosure encapsulating an inner cabin, wherein the cabin is configured to rotate between a raised position above a surface of a body of water and a submerged position, wherein at least a portion of the cabin is below the surface of the body of water, and wherein the inner cabin is configured to maintain substantially the same attitude as the support structure when the cabin rotates between the raised position and the submerged position.

This invention relates to a locking gimbal (10). More specifically, the invention relates to a locking gimbal (10) for automatically locking a gimballed object against motion arising from an external force (F.sub.E) applied thereto; and automatically releasing the gimballed object on removal of the external force (F.sub.E). The locking gimbal (10) includes a first object (12) pivotable about a first pivot axis (P.sub.F), a second object (14) movable along an arc cantered substantially at a second axis, a locking member (16) and a locking formation (18). The first object (12) defines a first reference axis (A.sub.RF) passing through the first pivot axis (P.sub.F) and a centre of gravity (CG.sub.F) of the first object (12), whereas the second object (14) defines a second reference axis (A.sub.RS) passing through the second axis and a centre of gravity (CG.sub.S) of the second object (14). The first and second objects (12, 14) are movable relative to one other between a first aligned condition, wherein the first and second reference axes (A.sub.RF, A.sub.RS) are substantially aligned, and a second displaced condition, wherein the first and second reference axes (A.sub.RF, A.sub.RS) are angularly displaced relative to one other. The locking formation (18), actuated by displacement between the first and second objects (12,14) is radially movable relative to the first pivot axis (P.sub.F) between engaged and disengaged position, wherein: (i) in the first aligned condition, the locking formation (18) is in a disengaged position and spaced from the locking member (16), permitting rotation of the first object (12) about the first pivot axis (P.sub.F); and (ii) in the second displaced condition, the locking formation (18) is in an engaged position and in contact with the locking member (16) thereby preventing rotation of the first object (12) about the first pivot axis (P.sub.F)

A hammock assembly for a sailboat may include a hull with a plurality of sides and a mast connected to the hull. The hammock assembly may include a frame comprising first and second frame members each having a proximal end and a distal end, respective first connectors connecting the proximal ends of the first and second frame members to at least one of the sides of the sailboat in spaced apart relation, and a second connector connecting the distal ends of the first and second frame members together so that the first and second frame members define a V shape. A halyard may be connected between the mast and the frame adjacent the distal ends of the first and second frame members, and a hammock may be suspended between the first and second frame members.
