the author suggests that U-boats were really quite stable in even very rough weather[quote]
That does seem hard to believe. I myself have seen photos taken from the bridge aft that show a u-boat rolling to (what appears to be)about 50-60 degrees in a storm.
40,000 ton aircraft carriers got tossed like rowboats in bad storms...
a 700-1200 ton u-boat would have been stable on the surface?
