Jeremy,
The next time you are on the hook. Have the cadet observe the swing of the magnetic compass during a tide change and or wind shift. Throw in a low Sun azimuth by telescopic alidade. If you still have that trusty NC 2 then compare the great circle calculation to a distant nav aid or point of land to protractor and chart visual interpolations.
