Most rigs use a simple shock cord downhaul to keep the pole from skying. The shockcord is attached to the uphaul where the pole is attached. THe other end of the shockcord is either routed through a block set into the front of the mast just above the deck level and back up the inside of the mast to an anchor point by the spreaders, or though a thru-deck fairlead just in front of the mast, down to the base of the mast and then anchored near the back of the centreboard trunk.
You need to select the correct size shockcord (diameter and length) to provide enough resistance to stop the pole skying, and stretch enough to allow the pole to be set easily. Usually, something like 1/4" medium shockcord works.
