The lake is very sheltered it is approx 20 Mtr deep where i have to put my mooring in, My boat is 7,500 Kg Approx 4.7 Mtr long
First of all, What a great forum I have done a lot of reading and have a lot of questions.
I have only sailed a mirror dinghy with my 14yr old daughter before so be gentle.
I am having to put my own mooring in my local lake (Lac Gurledan, Brittany, France) it is a man made lake which runs a hydro elec plant after a dam
What weight ballast would I need to sink to put 8mm chain to a bouy for mooring my boat
Looking to set up mooring temporarily on a lake with a sand/mud bottom. My boat is a 18 foot bowrider and weighs around 3200 lbs.
i have a 15 lb river anchor and a 15 lb navy anchor but don't have any confidence that will do the job. Looks like a mushroom anchor would be best but I cannot get my hands on one in a timely manner.
Could I take 4 cinder blocks, tie them together, and use a chain and rope with a buoy? Should be over 100Lbs?? I want a bit of piece of mind my boat will still be there in the morning.
Thanks for the comments. I was hoping to leave it over night for 2 weeks. But fair comments above so I guess I'll just launch and retrieve each day as I don't have access to get the right anchor while I'm here (Osoyoos Lake in Oroville, WA).
not much current here but wind has been strong each day.
You can do what ever you want . . . no telling if it will be enough, not knowing the actual conditions. If it is a mud bottom, you may not be able to raise the makeshift mooring after it has been in the water for a few days. If it were sand, then the blocks would probably just sit on the bottom (not sink into the bottom, like mud). . . not sure how much holding power that would be though . . . Keep in mind the 36 pound cinder blocks may only weigh about 20 lbs in water . . .

For starters my philosophy on the environment and recycling definitions is not just mine; it is a school of thought that is being instilled into each and every citizen of this two million strong Greater Vancouver Regional District. We have what are called recycling programs, for roadside collection we have the ‘Blue Boxes’ one is filled with recyclable plastics and the other is filled with recyclable food cans and glass jars. Then there are the ‘Blue Bags’ & ‘Yellow Bags’, the blue bags are for newspapers and other similar grade papers while the yellow bags are used for heavier cardboard grades. The paper and cardboard are taken to a plant to be broken back down into pulp and remade into new paper products, ditto for the plastics and metal cans, they too are melted down into their basic forms and recast into something new same goes for glass. We have depots for taking used oil, batteries, paint cans and other toxic waste to. We do not take old refrigerators, washers, dryers, stoves and other appliances to the dump, they are also picked up and taken to a recycle depot (they are re-incarnated as a brand new appliance or new car body). We pay recycle and environmental fees/levies on almost any recyclable product we purchase to cover the cost of these services. Nothing is intentionally dumped into the ocean like an engine block is. We call our province “Beautiful B.C.” or “SuperNatural B.C.” and we go to great lengths to preserve our natural heritage, we take pride in it. Are you being educated yet? Do you understand the majority definition of recycle? It is a far cry from your backward hillbilly definition. Here we maintain a forward progressive line of thinking towards the environment and recycling not the regressive backward thinking you propose.
We pay a high price to maintain this standard of living here and we feel it is worth it. I don’t know what state CT stands for in your Avatar signature but it must be an ugly place full of roadside garbage having people with your mentality residing there. Glad I am here and not there. You may think me an Environmental Wacko, perhaps you think all two million of us are, but we perceive you as an Environmental criminal who. (Offending remark deleted).
We do not use old used oil to water our gardens with and then claim this different use as our version of recycling, nor do we use old paint cans for containing a food in and call it our version of recycling just because the cans are put to a different use as you propose. Glass jars are not re-used, too fragile, they are smashed and melted down to become a car windsheild or house window.
Another example - We have these 4 litre plastic containers that are used for water or milk (yours would be one gallon), they are recyclable and can be placed in the blue bins for recycle but I also “RE-USE” them for ice packs in my cooler, I fill them with water and then put them in the deep freeze to use for ice blocks, in this case they are being “re-used” for another purpose, they are not being recycled as you would think, do you understand the distinction, or are you still confused.
Engine blocks and train car wheels are just down right plain ugly and do not belong on our ocean floor, they were never intended for such a use and their shape clearly indicates this. You can argue for arguments sake until you are blue in the face but it will never make you right. There are millions and millions of citizens who would not be able to comprehend your way of thinking especially if they come from a generation of progressive responsible thinking citizens. more

Lobster/Crab traps are no more dumped to the bottom of the ocean than shipwrecks are, both are there as a result of an accident, they are not intentional. Accidents happen by accident, moorings are deliberate and engine blocks are sunk intentionally. Traps are sunk with the intention of retrieving them with a live catch in them and then using them again for another catch for as many times as possible and hopefully not have to replace because they were lost.
Something “Trinkka” pointed out:
Are moorings really regularly inspected? One has to wonder in these tough economic times what services would suffer budget cuts, well I suspect monitoring/inspecting moorings would rank very high on the budget cutting list don’t you think? Once they are cut from the budget the chances of re-instatement become very slim indeed, so much for that argument. My guess is that many are lost, just like lobster traps.
Blocks become embedded in the harbor bottoms over the years, providing a degree of suction resistance in bottom material which has strong cohesive properties. Thus, a deadweight anchor is not likely to break free from its set. (An anchor is "set" when it becomes buried in the harbor bottom over time.)
Deadweight Anchors:
Deadweight anchors are commonly used in New England. They are usually blocks of granite which hold vessels in place because they are too heavy to be dragged or lifted by the vessel.
