    Wave 4:1 Main Sheet System Murrays Part# 28-041 The Murrays Hobie low profile 4:1 main sheet system for the Hobie Wave. By Adding a fairlead to the back side of the cleat on the base block we have made a low profile main sheet system that no longer needs a becket on the base block. We have also replaced the upper fiddle block with a double block which makes it even more compact. The result is a lightweight, low profile and very strong, made with 40mm Harken Carbo AirBlocks.
