Draw a line from 8 knots on the left-most line to the time in minutes on the right-most line from your waypoint. Where it crosses the middle line it will tell you how far, in kilometers, the convoy will go at 8 knots in the amount of time it will take you to get to your waypoint.
Draw a circle around the convooy position at that radius in kilometers, and then refine your intercept point out beyond that circle by 10 km or so. If necessary refine the distance the convoy will travel based on the new waypoint and adjust again until you arrive at a good intercept waypoint.
The idea being to get out in front of the convoy so you can spot them before they spot you and move your sub into an optimal position to slip past the escorts and get into the convoy to attack.

...this sounds interesting indeed, is there a diagram to go with it?
