Any one know a guy that does permanent mooring buoys . Howe sound area. Tried a few places but not having much luck . Feel free to PM me if you have any connections . Cheers
 
If you are able to borrow a sturdy wood raft/water ski float for a weekend, you can make and place your own anchor block.

Beach the raft on a low tide where you can access fairly close with a wheelbarrow. Put some 6 mil poly vapour barrier down on the raft decking, then use 2x10 to make a form 30" x 30" x 9", will take a dozen bags of premix concrete to fill. Set a big galvanized eye bolt in the concrete. Next day you strip the forms, let the tide lift the raft off the beach, position it where you want the buoy, attach rope or chain to eye bolt, and use a big pry bar to slide it off the raft.

That is over 400 lb anchor, and once it settles into bottom sediments it will be unmoveable.

Wish that was an option.

400 pounds of concrete is actually 240 pounds because of the buoyancy of water. Simple weight alone does not create a dependable mooring anchor. A flat concrete slab actually resists settling. Unreinforced concrete is not dependable and steel reinforcing will corrode. Much better, engineered designs such as the Helix, Manta or Dor-Mor mooring anchors are available. Quality hardware from the anchor is as important as the anchor itself.

I've used helical anchors occasionally for land based construction. No question they would work very well for moorage anchoring. Although I can't see getting the drilling equipment and barge time for only 1000 USD. Well, maybe if several were placed in the same area.

Anyway good point about shape and reduction of mass due to buoyancy. Mine only has to hold 19-22 ft boats a handful of days each summer and it's been fine for that.
 
The standard for an all weather mooring buoy is usually a lock block or a highway divider ( 4500-5000lbs) 5 feet of 1/2-3/4” long link chain with a 1” shackle wrapped through the block, 1-1/2” poly steel rope to the surface then mooring ball of your choice. A 5’ length of chain at the surface ensures no chafe on the rope from the buoy and makes the bout stand up straight

large shackles are a must as they are the weak link. The threads rust first then the pin loosens then falls out. It’s Important to use some lock wire or heavy zap straps
