Tie a 400mm length small line to the clew with a ring on the end. Pass the halyard from the snuffer through the ring and then up to the snuffer patches.
You will have use a longer spin halyard to make this work properly.
thanks Mike,
I realize now it's for the spin halyard/retrieval line slack, and not for the spin sheet excess when doused?
I'm now running the seperate tack where the bungee goes from around the halyard to the spin tack hoist line, so I may not need this?
I was thinking it was also for the spin sheet slack when doused?
