Silent Hunter 5 (SH5) - RAOBF and Attack Disk Tutorial - Part 1 - How?

Showing how to find a torpedo firing solution using only the RAOBF and Attack Disk. No map plotting necessary. This covers how to do it from the point of ship identification to torpedos hitting (or missing). Edit (2019-10-21): I never mention it in the video, but if you are using 1.5x zoom, use the red line at the 3 o'clock position, instead of the 12 o'clock when lining up the mast height to measure range. Edit 2 (2021-01-20): Mistakes are made. At 17:05, I put in the wrong AOB. I calculate 25 degrees, but I put in 30.
