Rope-directions.
Just after cutting, seems quite a bit of tension.

Possible Buoy, maybe just a long line.

-We don’t know the exact configuration (weight of concrete block, force of the possible buoy)
-Long connection around the DU might cut the VEOC.
-Connecting two or more DU’s lead to collisions and hooking (large forces)
-Sliding of the FAD line along a DU possibly leads to damage (Likely loosing clips)
-When really fixed to a DU the DU will try to lift the concrete at a certain movement.
-When fishermen come to collect their fish they use a large net (>>100m) and collect everything in it; ALSO THE FAD? And then get it on board (and pull an FAD fixed to a DU?) DU DU
