I'll check to see if I have plans for Druridge Bay ranges and see if Marker Floats were mentioned on similar ranges.

Some thoughts on the acronyms:
OHM: Outer Hazard Marker
If the O was a Q: Queens Harbour Master
Which would make KHM: Kings Harbour Master

Harbour Master sounds good but it sounds less like a military marker then.
The Druridge Bay plans I have don't show buoys let alone marker floats so unable to confirm or deny the use of marker floats there.

Peter,
That is an interesting observation. I recall from my RYA training that one of the tricks to know the direction of the tide and gauge its approx speed is to watch how the water impacts a buoy. With the standard tall round ones, they tip from the vertical and you can see through binoculars that the water is rippling up one side and lower on the downstream side.
The big cylindrical buoys in the Thames are yellow on top and black on the bottom so easy to gauge the flow from the angle of the line where the two halves meet.
With the design in the photograph the boat shape will swing with the tide and if it was hooked to a mooring buoy makes it very easy to quickly determine the direction of the tide. The speed of the tide under normal conditions is available from published tables. If it were intended to assist flying boat operations the shape of the boat-buoy and its relationship to its mooring buoy would be easy to spot.
I hope we have someone here who has seen one in action; it's an interesting puzzle.

Most moorings incorporated an swivel joint so it would probably have turned with the tide.

Is anyone on the RAF forum I linked to in the earlier post? They could question the person who posted the quote.

A photo of the various anchors used and also the swivel joints. The swivel joints would also prevent the chains kinking and would require regular maintenance, as would the chains and anchors.

I came across a reference to a marker boat in connection with a torpedo dropping range. As the target ship was also mentioned I assumed it was a different vessel. Target ships were normally moving so I have no idea where the marker boat fitted in.
PS I moved the Haile Sands posts to a new thread.

A few pictures of similar, although larger examples of such floats on the Yangste River in 2016

Those are more likely to be marine markers and I wonder if the boat is used to store batteries. Is there an international standard for marine buoys failing that does anyone have a sea chart of that portion of the Yangste?

The photographs show just a selection of the many hundreds(?) we passed. They marked the channel and obstacles. Several hundred miles from the open sea!
