Not a bad idea. If I remember correctly SH would give you a "green" crew to start or if you excepted promotion to a different boat - most times from one class to another e.g. Gato to Balao. You also received a letter of reprimand if your patrol was "below standards" with the knowlege that if you continued to perform poorly you would be releaved of duty and were if your next patrol was unproductive. I'm sure the respect factor of ones crew to the officers/Captain could be worked into that senerio also. Would make it interesting and keep you from just going back to base because you were having a hard time finding targets etc.
