Hint on hitting fast moving targets
 

Helpfull hint to use againt fast moving targets.

When tracking a target through the periscope, go to the "torpedo settings" panel on the lower left.

Now use the "spread angle" setting to adjust 1 degree for each 1/2 knot of speed of the target...aprox.

If the target is moving left to right at 12 knots, move the spread angle to right +5. Conversely if a target is moving right to left.

Also, if a target is less then 500 meters and moving fast, crank up the spread to +10.

This also helps if you are trying to hit a large target (battleship or carrier) in more then one area of the hull. To do this, make the first fish spread at 9, the next at 5, and the last at 3. This will distribute the pain evenly instead of hammering one spot on the hull.

Dont forget to save before fire, and F11 to see if the fish goes over or under the target, then load game and adjust to get the hit.
