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 separate 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?
No it's for the spin sheet. Think about it. Tie a small line to the clew, I use 2mm spyder line. The other end a plastic ring 1"- 1 1/2"dia.
Run the retrieval end of the spin halyard from the snuffer through the ring first then to the take down patches. When you snuff the spin the ring will be the first thing in the bag and will pull the clew and sheets in earlier than without it leaving less line out of the bag.. My small line is a bit longer and you might want to mess with to see what works for you. Shorter small line will take more sheet, longer less.
The retrieval end will need to be longer because the ring holds the retrieval line closer to the clew instead of going straight up from the bag to the first take down patch and you need the extra length on port tack so the retrieval line doesn't interfere with the shape of the spin.
