Hi there Psycho...
Ok as no one asked, what about tide and how much tide and what rate of flow for springs.
In Yachts where they have capacity for a few anchours, they will use grapnel or Admiralty for rocks and Plough for sand shingle and mud.
In any event, it depends on a few things. For yachts they recommend x5 max depth to lay out. However Yachts have a very large wind profile and weight so when they bop up and down they can Crab the Anchour bit by bit.
Firstly, it is the weight of chain that keeps the Anchour from coming under pressure because if it comes under strain, it will move. Ribs will require much less.
There is also the gauge or weight of chain, if in any doubt look at the big ships so this is another variable.
There is much writen on what will do but the best is to ask the local RNLI COx who will be deligted to advise.
