I have a 15' 500 pound sailboat. How much weight would be required for a
secure mooring in a small lake?

The old rule of thumb for mooring weight is 10 pounds per foot of boat
length. If you are on a small protected lake you could probably get
by with less unless your area is prone to very strong wind storms.
