Ya got to love those duck

real slow... yesterday it took me 12 hours of flank speed to overtake a ship (10kn). Perfect attack position (moving at 1kn about 500m off track 0° degree gyro when target is on firing point). When it changes course away from us about 1km short of firing point. Thus another 6 hours flank speed... again perfect position and then I get 2 duds
