I used a block with becket at the foredeck, so I get a 2:1 purchase, and a block with a snap shackle to be easily attached and removed from the pole end.
The problem is how to run the line to the cockpit. The first turning point is the U bolt used for the jackline where I fixed another block, then the line runs to the side of the cabin to a clutch deck block parallel to the line used to trim the genoa track. The system works well but I am thinking in using a couple of fairleads to avoid chafing the gelcoat
