Good post.For when the boat sits unattended (sometimes for days), I'm thinking that it's better to have a riding sail up than to have the boat constantly sailing.
In Block Island, RI this summer, in 30 feet of water that was right near 50 feet of water, I never got a good night sleep, in spite of having ample chain out. There was a good wind, roughly 20 knots. Back and forth, back and forth, back and... you get the idea. All night long I kept thinking of the anchor getting pulled one way and then the other.
Granted, the deeper water was upwind of us. It was still unnerving in that crowded anchorage.
