Thanks for the info Chris. I will try that.

I find it interesting that you use your windlass to pull the anchor  
loose.  You're not the first person to tell me that.  I don't have a  
windlass - I've got an older boat, before Catalina started putting  
them in. I have not gotten a windlass, in part because someone  
(possibly at Maxwell, or maybe it was the manager of my boatyard)  
told me that they were not really designed to pull anchors loose,  
only to pull up chain & line once the anchor was loose. So I figured  
I didn't really need it to pull up the slack line.

I pull my anchor loose by slowly motoring forward once I have  
situated the boat directly above the anchor & have (manually) pulled  
in the slack line, which is cleated on a bow cleat.
