inspired me to invent new U-Boot Waffe conception for kalois interested in extra long survival.

1. Never attack single ships or convoys after spring 1941 in misty rainy weather (view lower then 400 m) in daytime and nighttime too.
2. Never try to explore enemy harbors except deep harbors of volcanic islands, Curacao and Bridgetown for example.
3. Never fight with enemy aircrafts, Alarmtauchens only.
4. Never continue you way on the surface in bad view weather (view less than 2000 meters) if enemy radar was detected. If this is an aircraft you’ll fail to submerge unharmed.
5. Never attack convoys on calm seas at daytime (wind speed less then 4 m/s). Otherwise your periscope will be definitely detected. Wait for the dusk to come.
6. Never fight with more then one destroyer.
7. Never surface after first convoy attack. Fire all your torpedoes if possible, then go deeper then 100, turn off e-maschinen, no torps uploads. Stay deep and motionless no less then two hours.
8. Never come to artillery duels, you are not battleship commander!

Criticism and additions are welcomed.
