First, let me qualify my question: I'm fairly new to this whole thing and my experience base is very much lacking. That said, What am I missing?
I know the book solution for anchoring is 7:1 but I only carry 300 foot of line on my boat (and about 30 foot of chain on my primary anchor). To get 7:1 scope I'd have to anchor in no more than, say, about 40 foot of water and in the area I have anchored most (Thumb Cove off of Resurection Bay) that puts me about 100-200 feet off the beach. If I dropped the anchor at 40 foot and tried for a 7:1 scope I'd run aground before I could set the anchor, wouldn't I? Besides, the area can get a little crowded during our short season (it's a popular place to lay up) and I don't think there'd be room for every boat there to be swinging around in an area roughly equivalent to two football fields.
I know someone's going to laugh, but I truly don't get it.
