Sam, you must have been an Eagle Scout. I'm amazed that anyone is prepared enough to carry one type of anchor, much less two.

Anyway, I am still wondering what to use for rocky areas. I'm thinking maybe tent stakes. For regattas we used to rent a tent, and the guys putting it up had these really heavy-duty stakes they pounded in with a sledgehammer. (They are basically just really big spikes.) If they can hold down a tent the size of a three-car garage in strong winds, I guess they would hold a boat.
