SkiffRopes make 18 foot skiff spinnaker sheets from LIROS 9mm Magic Sheet and 3mm D-Pro. Cam splices 3mm D-Pro as a clew strop midway along the sheet to attach to your spinnaker. Cam splices a soft shackle cockpit joiner at the ends of the rope.
You can buy a finished SkiffRopes 18 foot skiff spinnaker sheet, using 9mm LIROS Magic Sheet, for $210.
You can buy a cheaper finished SkiffRopes 18 foot skiff spinnaker sheet, using 8mm polypropylene float rope for $110.
You can buy the materials to make your own spinnaker sheet for $120.

The Kitchen Maker 18 foot skiff team use SkiffRopes spinnaker sheet and have added Equiplite soft connectors to the halyard and clew strop to make rigging even faster.
