As the name suggests this system of mooring uses two or more anchoring points and requires a larger area within which to deploy the mooring assembly. Although there are more component parts within this system the reduction in the weight of individual parts means that with anchors at each end the mooring does not require heavy lifting equipment to position it. There is not a reliable or simple formula or recommendation that will allow us to say what weight of anchor will be required for a given size of boat within a specific location. Experience has shown that in very extreme conditions ‘multi point’ because of their inherent flexibility can generally be more secure than ‘single point’ moorings.

 Points to consider:

• Area of river bed available
• Size of Boat
• Expected conditions
• Depth of water
• Type of bottom
• Ability to deploy
• Ability to service

Hints and Suggestion – multi point moorings:  

A. Use either purpose designed single fluke Admiralty Pattern (AP) or stockless anchors.

B. Use the heaviest ground chain that is compatible with boat size and deployment capability.

C. Good quality used chain is often adequate for use as ground chain.

D. Lay two-anchor mooring systems parallel to the tidal stream.

E. Ground chain can be laid in two sections and joined at the riser-chain.

F. Do not over tension the ground chain, a little slack is desirable to reduce snatch .

G. Anchors should be ‘set’ in the normal way.  

You will need the following equipment:

· Anchors

· Ground chain

· Riser-chain

· Shackles and Swivel*

· Buoy

*Not required if you use a buoy that incorporates a swivel.
