Laying a mooring

[mitch]

Help needed please on laying a mooring in Chichester harbour.
For a 26 foot sailing boat. The area dries out at low tide.
What size sinker or sinkers should I use?
Is normal cement used for sinkers or is a special marine cement available?
I think it might be easy to use three or four lighter sinkers in order transport them to the site. Any feedback welcome.

Have a word with the harbour office. I suspect that they will have a minimum spec. Langstone certainly do.

If you can do not use cement. It is relatively buoyant in water. Try to get hold of a train wheel or two, or an old engine block.

The size of the sinker as no relation with the harbour where you will sink it.. :0)

For a 26' sailing boat and Winds up to 45 knots, you can expect a force of about 600 daN (600 kg)

Then if your sinker is in steel it should weight about 700 kg or 1090 kg ( 0. 436 m3) in concrete.. (or four time 273 kg) - Normal cement is OK..

The plate of concrete should be as large as possible and as I suppose the bottom should be mud in Chichester harbour, you can increase the efficiency of the mooring by giving a concave shape at the lower part of the Concrete block. To do that, before pouring the concrete, make a convexe shape on the bottom, using some sand covered by a plastic film..
