[I'm goin' down]

I set up a Cromwell attack. The ship was approaching from my port side -- the target's starboard side. I set up at a 45 degree angle, and checked it with the bearing tool to make sure my zero bearing was at a 45 degree to the target's track. I checked the speed of the target over a 3 minute interval. I set the scope at 10 degrees and turned off the PK. I sent the range to the TDC. As the target passed the cross-hairs, I fired 4 shots along its length. The torpedoes were set for 20 feet, within the target's depth. I set the AOB at 35 degrees starboard. All of the shots missed. I must have had the speed wrong? Any other ideas? I was set up for so long that I consumed three of RR's Mai Tai's, but I will save victory slice of cheescake for a later date.
