With regard to 'shooting' the stars and sun. You usually set yourself a disciplined timetable, but the weather can play havoc with this, so you must be able to take a reading at the best opportunistic moment - therefore no restrictions on where and when.

As an example:
In SH3 I set out from Kiel and set course to go around Scotland, down the west coast of Ireland. One day out from Scotland the weather closed in, and that was my last reading for about 4 days
I was then navigating on Dead Reckoning - course, speed and time, from my last know plot. I managed to get pass Scotland and was going south on the west coast before I got my next plot, some 4 days later. By dead reckoning I was about 50Nm out, and so corrected my course to go pass some small island.
I passed that island 24 hours later, 1 hour later than eta and about 5nm to far west.

This was my first RealNav attempt and ... I was chuffed

The only thing missing in SH3/4 are currents, tidal and otherwise. It'll be nice to have these.

i don't have SH5 (DRM @#!$!@%) but in SH3/4, Real Nav implied, no sub icons.. anything that gave you subs position away on the map.
