Using two PCs for "real navigation"

[Rosencrantz]

Has anyone used two machines for "real navigation" in SH IV? I came up with this idea during PCU Gulper (SS-228) test runs off San Francisco; one PC to run actual sim and action, while another with SH IV and its map installed is used only for navigation.

At the moment I'm planning to do "real navigation" in a simple way:

PC1 map (with PC1 I mean the PC used for actual simulation) is used only when "shooting stars" is possible (i.e. basicly at times with visibility good enough to get a fix). All other "navigational tasks" will be conducted using the PC2 map - even when there is navigational aids (usually land marks) availibe and especially when dead reckoning is used.

Tips and hints are welcome from experienced "real navigators". One thing I'm wondering is helmsman's abilities to stay on course... Not including attack runs and so on, played at TC 1, I haven't run any extended period of time without at least one waypoint. But I have noticed usually helmsman is having hard times to keep sub on exact course - but I'm not familiar with deviation issue in SH IV. Gyro had to be adjusted periodically in real life of course, but I would not mind find myself clicking compass rose every five minutes to tell helmsman to mind his rudder... Experiences?

However, I would not mind to get more or less rid off the present "GPS" navigation either...
