Re: mooring ball in a small lake
Call your local concrete dealer...chances are that those located near lakes make 'mooring covers' every day with any excess concrete left at the end of the day. For shallow areas like you're in, concrete dealers make 5" thick round covers about 48 inches in diameter, with one or steel loops attaching chain. They settle into the lake bottom so that they don't stick up and get hit by props...the settling in also makes them stable and not moveable unless they're freed up or lifted with a crow bar. Just like an anchor, it isn't just weight that keeps them in place, although they're about 300lbs, you can roll them out to where you want it. Myself and all my neighbors use these, two adults can walk (roll) the mooring into place. Mine is in 4 feet of water, and occasionally get shifted by ice so you may need something that can be relocated easily.<br /><br />Use the correct tool for the application...round steel mooring caps are also sold. Skip the engine block or other massive piece of junk notion that would be near impossible to move or remove when necessary.
