More anchoring questions:

What is the best point on the boat to attach the anchor line? I know the big cats and tris usually rig a rope bridle from the bows, with the anchor line attached to the center of the bridle. Cats and tris tend to "sail" at anchor even with no sails up, just from the way the wind catches the hulls.

Also, should the mast be secured centered, or allowed to rotate freely, when the main is up? When the main is down?

Also, should rudders and boards be all the way up, or what?
