Don't forget the training time neccessary to man the new boats. Even after the production kinks were worked out, the boats required lengthy workups in the Baltic. They were totally unlike any other U-boat, so crews had to be completely retrained. This was one of the chief factors in the abandonment of the Walter boats as well. Their H2o2 fuel systems were dangerous and learning to operate them safely would have taken months.
