Meters or Yards??

For those unfamiliar with "high-scoping".
Due to the inherent design differences between a US Sub and Uboats, the conning tower of the US boat was taller and if you look at the periscope sheers, the metal support casings for fore & aft scopes, there are "look-out" platforms on port & starboard sides and abaft of the sheers.

"High-scoping" was performed while the boat was surfaced by a watch stander inside the conning tower.

As you can see, 9 nm...Thats 18,000 yards(16668m) on a clear day. Gene Fluckey, in Thunder Below!, describes three instances of "Atmospheric phenomenon" occurring when travelling in the Kurile Islands and up along the Kamchatka peninsula, where they could see Japanese convoys 26-50 nm away through the scope. These same phenomena are known as Arctic Mirages, reported during the first Polar expeditions.

edit: sorry, didn't mean to drift from the topic.

The International Extraordinary Hydrographic Conference of 1929 set the standard of 1 nm = 1852m; however, individual nations all use nautical miles when measuring linear distances over water on charts. Why the Devs chose a land-based measure on the F3 chart is not in keeping with nautical protocol. So, we just live with it.
