I have done this in SH 4. Plotting without your sub icon is not too much harder than doing it with the icon, except you must plot your own position and keep careful track of your own course and speed at every minute. Also, any turns you make must be estimated and thus your plot will have more errors than otherwise. This I think is the biggest disadvantage. It is very difficult to estimate the turning radius and turning speed, and this more or less precludes making turns while your are obtaining estimates of speed and course. (Submerged evasion will likely make your plot into speghetti.) If you find later that your plotted location was way off, you can always erase it from your charts, so it really doesn't matter it your initial DR position is accurate or not.

You can also make your plot on paper, but this brings the added problem of having to transfer your points when you run off the edge of the paper.

When I plotted hydrophone bearings, it was more for the purpose of closing to tactical range, than trying to obtain a firing solution. If I'm close enough to see the target, that is how I do it.

Personally, I gave up on the Celestial Navigation. It was too much work and painfully tedious. Doing a tactical plot without any of the map-contact cheats is some work too, but you don't have contacts to plot every day, while the Cel Nav thing just wares you down.
