And 1/3 speed is a bit loud. They could have heard you. There are a number of reasons they found you.

Thanks for the reply bstanko6. BTW, believe or not I am subbed to your youtube channel and I have learned the best sub-driving skills only thanks to your videos.

It was day 10AM, 3m/s wind, no fog. I was down at 50m ~ 60m, doing 1/3 ahead. I wouldn't dare putting up my scope right next to a PT boat in a broad daylight...
I swear I was able to walk out of the scene very easily in my old GWX 3.0 games a few years ago. PT boats? Dive to 50m and run, no problem.
This time my boys called 'we are being pinged sir'. I just can't believe a small elco boat in 1939 december carrying an ASDIC...
