It's was originally called a "Douglas Protractor", I started celestial
plotting using one. It and a circular calculator( the black ones with
semi-luminous markings) were taken by someone who needed them more.

The current Linex 2802 protractor has the raised printing on the
reverse side, so it tends to wear off if left loose in the Nav drawer.

I currently us a pair of 45-90-45 triangles for all my plotting.

I was told, by a WWII Merchant Marine Captain, that prior to WWII the
order was given to move the stern in the desired direction. This was a
carry over from the days of tillers when to turn to port, you pushed
the tiller to starboard. Anyone heard any other stories?
