That's 100 fts. I don't think someone could survive just being ducked at thirty meters (Decompressions and all that)... If so, it's amazing. Could you check the numer?

Sure, no problem. It was a book from a local public library, but I can check it. Wan't to be sure my self.

I don't think that decompression would be a "big" problem. THe italian Gianluca Genoni has dived to 133 meters without scuba gears and it's a world's record I think. So that is a 100 meters deeper than in this U-Boat case.

Decompression and that only works when you spend some time at a certain depth... scuba divers go really deep (I think the world record is something crazy like 200m or so!) and they dont do any decompression, because they just go down and then up.

Anyway I have also read about watch crews being submerged for some seconds, this one must have been really scary!

So I wen't and checked the numbers from the ShÃ¤ffers "U-977"

It happened pretty much as I told earlier, there was a terrible storm going on and ShÃ¤ffer was one of them on the bridge. They used to yell warnings everytime a huge wave was about to crash down on them so everyone could prepare for it...When the boat was submerged, he (ShÃ¤ffer) wandered how much longer they would have to be under water and he wanted to shout "Alle Maschinen stop!, anblasen!" but couldn't of course. He hoped that the LI would be alerted and knew what to do and fast. Finally, after long time the bridge surfaced again, all machines were stopped and compressed air hissed into divin tanks. The hatch opened and the LI grinned to his captain and asked if everyone was still there and alive. The boat went to 32 meters and six tons of water rushed in the boat through the valves during the dive.

He (S) said also that it wasn't unusual if the boat would dive to 15 or 20 meters in storms....
