This is a method that works if the sea bed is not that deep. You begin by making heavy concrete blocks which are then tied to the dock using a chain and dropped into the water. The chains are adjustable and can be made longer or shorter at any time, depending on the level of the water during tide fluctuations. 

This is a very effective method that ensures the dock maintains some level of freedom in movement, but it cannot be swept away no matter how heavy the storm may be. It also means that the floating dock cannot be pulled into the water since the length of the chains can be adjusted at any moment to compensate for any changes in the water level. The only drawback is that it cannot be set up in deep waters.

This will have to be a considerably long gangway for it to reach out into the open waters, but it is a possible project to pull off. What you will need is to set up a very long walking path that is protected. This boat dock ramp will also have to be very solid to avoid being swayed around by the waves. This could be achieved by anchoring it to the floor of the riverbed if it is shallow enough. The bottom line is that it has to be long enough to connect to the floating dock out in the open water and at the same time be deep enough to allow a small boat to approach the land.

This is another long shot technique that involves setting up a boat lift system with cables that extend all the way from the shoreline to the center of the floating board. This will work best if the floating dock is not that far out in the open waters as that will require a very long cable which will bring about some structural integrity issues. The cables can be tied on a solid anchor on the ground then extended out into the water by being supported by pillars along the way to stop them from dropping into the water. For this reason, this setup can only be used in shallow waters.

Strength of Waves: The strength of the waves should give you an idea of the type of boat dock construction anchorage to go for. Places that experience very strong waves will need more robust methods of keeping the floating dock secured in the open waters and vice versa.

Local Regulations: Setting up structures as big as floating docks require persimmon from the local authorities. You have to be aware of the laws your locality has in regards to setting up.
