I would hope spy ships are better camouflaged
Ships no longer required; almost everyone carries a tracking/listening device with them at all times.

Paul,
"I always find that a very interesting fact, I often ask people to estimate the distance and they think its 30 miles or more!"
There's a simple calculation to figure out how far the horizon is although you'll probably need a calculator to work it out quickly:
d = 1.22 * sqrt (h)
where d = distance to the horizon in miles and h equals the height of the observer in feet. So, for someone 6 feet tall standing at sea level, the horizon is 3 miles away. Top of Mauna Kea gives roughly 145 miles and on a plane at 35,000 feet, it's around 230 miles. This doesn't include atmospheric effects such as refraction but always found it useful when figuring out what I can see, especially on flights.

Thanks! In new money that’s
d = 3.57 * sqrt(h)
With d in km and h in metres.

They must see a lot of spy ships up on MK.

We've been lucky so far that China hasn't found a way to get their spy ships up to MK unnoticed.

It's not through lack of trying.
They just haven't been successful ... yet.
Here's recently declassified footage shot by Werner Herzog, of an early attempt to pull their spy ship (obviously) up an undisclosed valley on the Hamakua Coast:

Remember TomK, you're Big Island's last line of defense from Chinese spy vessels. Don't forget to look down occasionally, as well as up.
