Has anybody made a mooring anchor? I am moving my boat to a high mountain lake after the Nationals and need to make a mooring anchor. I found a web site called http://www.mushroommooring.com/index.html with some good information but would prefer not to spend several hundred dollars on an anchor. According to this site it takes a 250lb mushroom anchor to hold a C250. Plus a heavy chain 1.5 times the water depth with a lighter chain the length of the water depth.

I wonder if 4 90lb concrete filled 5 gallon buckets with a 30lb plus mushroom anchor?

I think we have used tires filled with concrete, big eye bolt in the center.

In a harbor on the other side of my state, the favorite is surplus rail car wheels. Apparently, they're suitable for a boats a fair amount bigger than a C-25.

On public waters, be mindful of regulations... there are lots of places where you can't set a mooring without a permit. Are you going to have to retrieve this anchor at the end of the season?

You can also try setting 3 Danforth-style anchors at 120 degrees from each other, connected by chain to a swivel at the center of the circle and a lighter chain riser to a float and a nylon rode to the boat.

looks like it might be easier and less expensive in the long run to buy the correct size mushroom- where do you buy a wheel from a railroad car anyway?

In the Glenan's manual they describe a mooring anchor as a flat and square concrete anchor no more that three inches thick, with a rebar loop in it for a swivel. Making three of these at 90 lbs each would make them easier to handle and give more edges to bite the bottom. Has anyone had any experience with this type of anchor?

for thirty years we moored our cape dory 25, catalina 22 and the C25 in succession to a V8 engine block sitting on the bottom of the St. Marys River. In all that time it held fast. Two summers ago in a heavy blow I watched as the boat began to wander down stream dragging the faithless motor. I rowed out and brought her in to a neighbor's dock where she stayed for the balance of the summer. last summer I had a new dock built so I would not have to use a mooring.
The problem in the St. Marys is the ship traffic. When thousand ft. freighters pass they create such suction that in the recent low water the bottom is so disturbed by the wash that I imagine the V8 was washed free of its muddy hold.

My advice on mooring is to use lots of chain.
