Abstract
The transfer of elongate objects across a gap is enabled by doubling a jackstay between a supply station and a receiving station, so as to provide a pair of parallel guides for the load during transfer. The load is supported from each of the parallel jackstay portions, such that its length is normal to the lengths of the jackstay parallel portions, and moved by outhaul/inhaul cables.
