Hi Wxup - Most of the time I pull my Getaway up on the beach, facing the wind, rudders up, sail loose and it never goes anywhere. When we rent larger cats in the BVI's, we use a bridle, rudders are down, sails are usually down and again the boat stays put. I also have a Corsair F-24 (trimaran) and before I started using a bridle, the boat would sail past it's anchor all the time, unnerving if you plan on going to sleep. I now anchor with a bridle, boards up, rudder up and sails usually down and I don't have any problems.
If I was going to anchor the Getaway for a short stay, I would be comfortable with a bridle, rudders up, jib furled, mainsail up, slack in the sheets and uncleated. I'm not sure I would disconnect the main sheet from the sail either. Too easy for some one to get popped if the wind picks up. I also wouldn't wander far off. Stuff happens on the water, count on it.
But if you have sand, put the boat there. It's safest, easiest and the boat is made for it, you can't hurt it. Have fun!
