Re: The physics of a mooring ball...
I can't imagine a mooring ball offering any sort of help as ground tackle.
It's job is to allow you to find the darn thing when you get back. It might double as an aid to keeping the rope bits out of the mud or a place to put your identification.
You don't really "need" a big buoy unless someone with authority tells you that you have to.
I've used both a big round floaty thing and a lobster pot type float and found the only difference is that the big round floaty thing will bang against your hull when it's dead calm and keep you up all night.
