A good tutorial there for Intercepting just in time :

And Math speaking in general ( From my archives ) :

ANGLE TO INTERCEPT

================================================== ====

To calculate the angle you need to turn from to intercept the contact. You should use knots as the the u-boat and ship's speeds.

Angle to intercept :

Sin-1 ( Target's speed * Sin ( AOB ))
= -------------------------------------------------------------
u-boat speed

now use this formula to calculate the angle you need to turn from to intercept the contact. You should use knots as the the u-boat and ship's speeds.

If my u-boat is traveling at 12 knots and the contact is traveling at approximately 5 knots :

Sin-1 ( 5* Sin ( 123 ) / 12 ) = 20.4534 Degree

And so the angle I need to turn to intercept the ship is 20.4534 degrees
