100-150 feet is usually okay.Balao and Tenchs could go well beyond their test depths of 400 feet(600 and even deeper in some cases) because of their thicker hulls, although I think in RFB can only go to 450, hopefully they will implement the deep dive function like in TMO at some point, where can go to 600 feet and beyond..Gato and previous classes think 100-150 feet below test depth(red line) is fairly safe.Wouldnt do it unless forced to during evasion.
