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



I don't know. However, I can guess. I figure the concrete blocks used to
moor 30,000 lb. and larger boats in an ocean harbor probably weigh about
600 lbs., I suspect it won't take too much to hold your 500 lb. sailboat.
The mooring blocks sink into the muck on the bottom, adding to their holding
strength that is from an angle.
