Just as the crew was sitting down for dinner, we received a hydrophone contact of a merchant that was closing. It was another large old split freighter, travelling at 10 kts. We attacked, firing torpedoes at a thousand yards at 90 degrees. The attack was recorded.

We used SCAF/manual targeting and released the first of four torpedoes at 346 degrees. The range and aspect ratio at 1800 yds was dead center using SCAF so I lowered the periscope (practicing for the more difficult attacks that are sure to come) and tracked the ship on the Attack Map. I did not recheck the aspect, course, range and AOB for accuracy after that point. The first torpedoe made contact dead center splitting the freighter in half. The other three were fired after a slight delay and released between 350 - 356 degrees. They each missed aft of the target - the second shot by a yard , the third by 3 yds and the fourth by 3-5 yds. All were fired using slow speed torpedoes. I cannot account for the missed shots, except to note that the torpedoes were set at slow speed (I did not have a high speed option) and I did not recheck the SCAF for accuacy within 1800 yds. In any event, the missed shots were close misses (I know--we are not playing horshoes!).

I have concluded that SCAF appears to work quite well, and I recommend it for the reasons posted here and above. Certainly working through Hitman's tutorial is well worth it because it explains the concept and importance of aspect ratio in a submarine attack. I am glad I read it because I would never have understood SCAF without working through attacks using Hitman's method. How he figured it out is beyond me, and he deserves credit and praise for explaining and presenting a complex subject in a fashion that a lay seaman such as myself was able to understand. Thanks Hitman.

Next objective, attack at an odd angle using SCAF where the shot is not a broadside, as demonstrated in Hitman's tutorial example. Previously, I thought that tactic was an impossibility.

That's it for this thread unless someone has questions or comments that are appropriate to address.
