Works for seaplanes so you need a proper mooring buoy with
clear space 360° on each airplane.

For seaplane and boats too, if you have a permanent
anchorage, try heavy chain and three anchors at 120°
spread.. You can use four big concrete slabs as dead weight
or three Danforth type anchors, connected to a center
weight. A large diameter nylon rope from the center point
to a buoy, with points to tie-up. If your water is subject
to tides, you need to allow for this change in water depth.
The heavy chains keep the forces on you anchor normal to the
bottom and the mooring buoy will have limited swing and
still hold against wind and current changes.
