Often while cruising to a waypoint I will get a message stating something like convoy detected, location xyz, heading NSE at 6 knots. I then change course and head for the location as noted and find nothing. I've attempted to "zig zag" across the general last reported area and never locate the convoy. What am I doing wrong? Thanks - Kim

That's where they were. You need to figure out where they are. There's a chart that converts knots to km/hour, then project the convoy's position out at 1 hour intervals (hoping they don't change course). Then figure where you want to intercept based on your speed, time of day, weather, etc. Head there (before they get there of course) and sit and listen. I'll try and find that chart.

By the time you get there, the convoy has moved on, you have to head it off, look at the convoy marker's course and and draw a rough line through it with the ruler tool, then full speed ahead to a good interception point (look at the paper map with the convoy routes marked on it, it should give you a rough idea of where the convoy is headed.)

Even when reach you interception point keep moving, dive every few moments and listern out for it on the hydrophones, whilst surfaced you can recharge and hope that BDU updates you on its position.

That said, it really depends how far away you are from it, generally your sub can do about 17 knots surfaced - while a convoy only travels at about 6 knots

JU88, you are way more experienced than I, but I say there's no need to hope for BDU updates. If you extend the course, calculate km/hour based on given speed, you can figure roughly where that convoy's going to be at any given time...until they change course. Plot a sharp intercept and go straight to them!

Thanks for all the good info! I will give it a shot...I tried to "bead" off and estimate where the convoy may be going but have had zero luck.

Guess practice makes perfect.
Thanks again,
Kim

Yes practice makes perfect but you must also practice perfecting what and how you do it.
Start with the printed map so you can be in the convoy routes. I head out just to attack convoys and only attack single ships that are easy to find in my path. I attack one or 2 convoys on every patrol.
As mentioned above, when a convoy is reported use the ruler tool to draw a line. You can then use the tool to draw a line from your position to the end on you convoy line and check the two distances. Note the speed of the convoy. Not all convoys are 6KTS. Some are 7-8-9 even a few that are 14 knots so see what the speed is. If it says slow, then assume it is 7 so you are sure to get in front of it.
As you move toward the convoy dive and check position by hydrophone. Once you make contact do not come straight in move a little to the side, go to silent running. If you come in from the front the escort will pick you up on sonar. If you come in at a 45% angle, he will not. Slip in behind him and move toward the middle looking for the fat tankers. Keep your periscope as low as possible so the merchants do not see you or they will alert the escorts.
This is the most tense and most fun part of SH3.
