Here’s what works best in our area: The depth of the water you will be mooring in is really important, the deeper the water the better. Cement louses 62% of its weight in fresh water, so you really have to over build it to get any real holding power. Next is surface adhesion, the broader the bottom of the weight, the better the holding is. If your determined to make your own block, then head down to the sand pile and carve out a cone shaped hole, put in a large eyebolt and fill it with cement. The end result will be, a giant cement Hershey Kiss, the reason for this shape is so the pennant can’t catch on it and abrade and the you dramatically increase the surface tension. My preferred mooring consists of a granite blocks a foot thick with two holes in it, 6’ of chain looped through with a swivel and a nylon rode (length = 1 ½ time the depth). The appropriate weight for your size boat would be 1000lbs.

An iron mushroom mooring simply won’t work in the lakes unless you grossly oversize it, unlike the ocean where they can work down into the bottom with the tidal currant changes. They just roll around on the bottom in the lakes until they catch on something.

BTW: you will need a mooring permit if you’re in state waters. It may take a while for them to catch you, but they will. They most likely will post a 15-day notice on your boat before they impound it….
