Hello all, I have been creating my latest historical mission, Hipper and convoy JW51B.......but the times that the ships reach their waypoints doesn't work out. Yet in the real battle the times that the ships took to each waypoint did work out. If I start a destroyer at 30 knots initially it does 30 knots until it gets to its first waypoint and then slows down to 5 knots. The destroyer just won't maintain the speed of 30 knots from waypoint to waypoint to the end of the waypoints. This problem doesn't seem to be related to the wind, weather or visibility as to why the ships all slow down. Does anyone know why this happens ????? Thank you all, Erich Topp U-552
