1. I have started to sprint ahead of the convoy and get in position to run an attack but be well outside of visual range. come to an all stop and submerge to about 30ft. This way your decks will be awash but not the conning tower. If possible make sure you are oriented along the convoys path so that you will now present a very small visual and radar profile to the enemy. BE PATIENT. Keep your targetting binoculars pointed in the direction that you expect the convoy to appear from. You should be able to get a visual on the three merchants needed to be able to send of the report before you are spotted. I find that it helps to watch the behavior of the escorts on your map or radar screen to tell whether they are just trolling along or actually running detection patterns.
2. did you stay within 50nm of the designated patrol point? (try drawing a circle around the star to ensure you stay within that perimeter.
Happy hunting
