How do PT boats manage?
The real ones or in AH? In AH I use the CBDR technique. CBDR stand for Constant Bearing Decreasing Range and ship captains and aircraft pilots are keenly aware of it because it means they are on a collision course. So that's what I do: set a collision course for the torpedo and the target ship. I first set the PT speed to equal the torpedo speed: 40 mph. Then I lead the target ship by quite a bit and run for awhile with the #3 gun pointed at the target and then left in place. If the target slowly gets ahead of the guns direction then turn the PT to lead the target more and reset the gun to point at the target. If the target slowly falls behind the gun bearing then turn the PT to reduce the lead and reset the gun to point at the target. Keep repeating this until the target ship stays perfectly aligned with the gun bearing. Then keep running until you get relatively close, then drop the torpedoes. If the target ship doesn't turn, you'll hit it every time. Note that if at the beginning the target is going away from you, even at an angle, don't bother: neither your PT nor your torpedoes will ever catch it.
