A pipelay vessel has a crane 6 having a base 8 with a hollow interior and a stinger handling system 10 for handling a stinger 2 extending from the side of the vessel. The stinger handling system has a link 12 extending out through an opening from the hollow interior towards the side of the vessel for connection to the stinger 2. The link is arranged to transmit both tensile and compressive loading. A jack structure (24, fig. 2), located within the hollow interior of the crane base is mounted to extend and retract the link 12 from within the crane base to raise and lower the stinger 2. A universal coupling (fig. 4b) may be provided for self aligning the link to the stinger in the horizontal plane. The crane can be a tub crane with a circular or polygonal base, with a vertical slot to allow tilting of the link during extension and retraction.
