But that does bring up an interesting question, what's the biggest ship
that's been sent to the bottom by seas? Not icebergs, U-boats, or
collisions, but by good ol' Mother Nature, other than turning the Cape and
meeting up with the rocks, just out on the open blue water. Will have to
look into that...

This typhoon and it's effect is interesting, but no ships as big as
"Derbyshire".
