Get two anchors with a length of chain between them and then come off the middle of this with another chain to your buoy. The length of the connecting chain depends on the local conditions and weight of your boat, for my boat (2Tons) I used 12 mtrs.
This can be difficult to lay but the trick is to lay one anchor as you would normally then tie a rope to the heel of the second anchor and lower it to the sea bed will pulling it in away from the first anchor, this is best done at low tide. Better still dive on the second anchor and push it into the sea bed. The rope you tie through the heel should be fixed in such a way that you can release it, slip knot or loop etc.
Lay the two anchors inline with the current or prevailing wind depending on which you think will be the greater. Whole cost about £150 for parts
your time while on holiday
Alternatively pay the marine £12 a night which will be cheaper, safer and easier
