Don, I have done this!! It never really holds very well though, which may be another clue that my setup is wrong. It's gotta be the setup, because there's plenty of mass there for holding power. 8^)

I'm gonna check it again, but I also have another question: Does everyone run a cleat on the spin halyard to lock it in the sock/snuffer? The fellow I bought my boat from did say that every now and then the wind had unexpectedly grabbed the head of the sail and pulled it out. My boat doesn't have this, but the newer infusion at my club does. Is this a worthwhile addition, or does it just make it a PITA to raise the sail? I always pull the head of the sail completely inside the sock so I'm not sure it matters.
