I finally got an anchor sail. It's a beauty. I've been flying it for the past few days and it really diminishes the amount of sailing-at-anchor that we do.
I took it down tonight becasue I'm not satisfied with how I have it attached to our rigging. I'm currently using some small line to attach it.
I don't want to mess-up my rigging, so I'm not planning to use a stainless steel shackle. Maybe my concerns are groundless, but I figure I'll get some strapping, like that used for jacklines. Maybe a softer metal would work too.
What do you use to attach your anchor sail to your backstay?
