Odd navigational marker

[svBeBe]

Recently along the far southeastern Turkish coast we encountered a navigational marker that was new to us.

It was a large cone shape painted red over green, with a 1-meter circular base painted black. Sticking up over a meter above this red & green cone were 2 black circles, placed about 1/2 meter apart, 1 directly aligned over the other.

Can anyone tell me what this marker means? I cannot find it in any of my reference books.

The two black circles sound like and isolated danger mark. But the red over green, sounds almost like a preferred channel marker (minus one stripe), with the recommended channel being starboard due to the cone. Not that I have the answer, my guess may be a combination of the both. Any photos?

[svBeBe]

No, we did not get close enough to take a photo. Since we didn't know what it meant, we stayed well away from it.

The idea of an isolated danger mark seems logical to me. This was nowhere near a channel of any sort.

If it had two black vertical spheres, and red and black bands below, I'd say it was a marker for an "isolated danger", but the green band throws me off.

Was definitely bright red on top half of the cone; green on the bottom half of the cone; and wide black base.

Like I said, we have never seen anything like this. Guess it was a marker for an isolated danger (sunken gulet, maybe?).

What you describe isn't on any of the IALA-A charts that I've dredged up on the Interweb. Did it have a flashing light?

Two black spheres is definitely "isolated danger" and would normally have a black-red-black base. Red over green is "preferred channel to starboard. Maybe it's some kind of local kluge-up of the two.

Didn't look like any of these; except for the 2 black circles high atop the cone. It was a large cone shape. With the top half painted solid red and the bottom half painted solid green; no line separating the 2 colors. The large circular base was black.

We looked up the same ones you show above. That is why we were confused. Cannot find any reference to a buoy like we saw.

But it was clear to us that if you don't understand whatever is meant by a marker that you should stay well away from it.

I think we can all agree on that. Is it possible it was a private (non-IALA) danger buoy?

Or something obscure like "dump zone with pointy, awash rock in the middle of it"?

Yeah, I wouldn't want to speculate closer than 200 metres off!
