Navigation in bad weather

[Tupolev]

Hi all.

I spend quite a bit of time with this game trying to find ever new ways of playing more historically, or realistically. I remember someone posting here on an old thread about the advantages we as simmers have considering navigation and "getting lost" on the open ocean.

Knowing very little about navigation on the open ocean, I'm guessing that the only real way of plotting ones exact position is use of the Sextant and taking sun shots. If the weather is overcast/stormy for an extended amount of time you'd be down to ded. reckoning and subject to drifts, etc. So basically, you wouldn't be sure of your position.

I'm not quite interested to the point of jumping into the RealNav mods, but more the implications of losing one's exact position. I guess the point of my lengthy post is purely a question to those who would know more about real navigation:

If the weather is overcast/stormy for an extended period of time and I get an in-game radio position of a convoy, would I be able to (realistically) plot an intercept with a reasonable chance of success without the sun shots?

Was there another way of fixing ones position I'm unaware of? Radio bearings from land maybe? Were the drifts and currents in open ocean enough to render ded. reckoning unusable?

Or am I just way over-thinking the game?
