Repairs and Fatigue
 

I have noticed crews get fatigued far too quickly, couple hours at GQ and 50 percent fatigue? Have no idea how to adjust this. Also, noticed damage not repairing in spite of having the "master mechanic". Don't mind the destroyed torpedo tubes not repairing but have one at 95 percent and another at 84 but neither is being repair in spite of orders to do so? Been two days since they were damaged by depth charges.

KaleunMarco has a pdf download in the SubSim downloads section...

Edit: Found it Eliminate Crew Fatigue - I don't know if it will speak directly at what you're after, but it should get you in the correct area, maybe even the ballpark...
