To date, the deepest I have dared to take a balao, has been the 700ft mark. Almost impossible to control the helm though. Had to run at flank speed, and when the batteries started to diminish, and speed dropped below 7 or 8 knots, I had to get the boat up to 500.
Constant hull noise was quite un-nerving too! Toughest part was getting the boat to rise from that depth. It seemed to take forever to start the assent. So I don't go passed 600ft now, unless it's absolutely necessary.
