Discovered a very useful technique for anchoring with all chain.
Here it is.
Get yourself a mooring compensator like this:
Rubber Mooring Snubber - Taylor Made Products 2019 Catalog
Use the appropriate size line and compesator for your boat. The line should be about min 30' long. Do an eye splice at one end. Attach your chain hook the use the small eye.
Next set up the compensator so that its 4-6 feet from the eye splice/chain hook. For safety... add a lobster float at the end so if you drop the snubber one end is float and you can retrieve it.
Drop your anchor... chain should be marked. I have marks at 50, 100 and 150 feet for 200 feet of chain. lay out the correct scope BASED on the depth... not the free board ht.
Next hook the chain hook of the snubber line to the chain at or just aft of the anchor roller.... wherever it's convenient to reach.
Lay down more chain holding on to the snubber line until the chain hook has disappeared below the water. The conpensator needs to be ABOVE the water so you can see it. Now lead the snubber line to a cleat and tie it off.
Next lay out more chain and the snubber wull be taking the anchor load.
Here's what the compensator will tell you.
Assumes decent wind force or engine in reverse... so boat is pulling after on the anchor
ANCHOR NOT SET
mooring compensator DOES NOT unwind and DOES NOT stretch... you may be dragging or the chain is in a pile at the bottom.
Mooring compensator DOES unwind and DOES stretch. This tells you that the anchor is set and resisting (holding the boat) the force of the motor or the wind. The more it unwinds... the more it stretches... the greater the force on the anchor tackle.
The mooring compensator will tell you IF your anchor is set or if it not. PERIOD FULL STOP END OF STOREY.
NOTE: The anchor could break free in strong winds. If it does the compensator will show no stretching and no unwinding. So if it gets windy... go forward and observe the compensator as it's telling you if you are set or dragging.
This system has not failed me once in 25 years. BUT IN STRONG WINDS AND / OR CURRENTS YOU NEED TO PERIODICALLY CHECK THE COMPENSATOR.
