The value of determining exact "known" position by making a visual sighting of any land mark, cannot be over stated as errors in location would compound over time on the open ocean.

Sofu-Gan was a favorite land mark during submarine deployment across the Pacific into Japanese waters. I would certainly advise using it to set your known position and thereby eliminate any errors to your position that had accumulated during the initial crossing.

I, on the other hand have no problems leaving the navigation to the game- or to the professionals assigned that task... as most commanders did in real life. He had enough to worry about anyway.

Very useful, thanks!

Did RFB include Sofu-Gan, or is that a standalone?
