One of the theories behind the tragic sinking
of the famous freighter Edmund Fitzgerald is that she was downed by a
rogue
wave during a major storm on Lake Superior back in November 1975. No one
will know for sure as everyone perished. from an article in Boat/US
Magazine

From the same article about waves in the ocean that just poof there it is
,
not even a storm....

Imagine cruising on a perfect sailing day and suddenly staring at a 35- to
40-foot wave that comes out of nowhere. "I remember as a boy cruising off
of
Cape Hatteras in a calm sea, seeing a rogue wave come out of nowhere,"

This hardly describes the wave(s) that destroyed the Fitzgerald.

IIRC, it was 100 knot winds over shallow water. Imagine a nosedive into the
lakebed 200 feet below (for a 700 foot ship).
