I used to do a lot of map plotting but I got lazy and get the officer to calculate the speed for me.

I've recently become even more lazy and often just estimate the speed based on eyeballing it, using the size of the waves off the bow and the wake, works well enough close in.

My biggest problem is all I seem to be able to find is Destroyers, the North Western approaches just seem to have enormous convoys of Destroyers who don't detect me even when I'm on the surface. I pick off one after the other.

If you're calculating speed using the Hydrophone, how do you get an accurate distance to plot with the bearing?
