According to the Government they figure 200' swells possible in the Bering
sea area. Spent a few deficit dollars looking at them with satellite radar
to figure out how to measure and keep ships out of their path.

G Picture a submarine, diving.
Judging wave heights, at sea is not easy. On a ship, judging heights up
to @30-40' can be done with reasonable accuracy (the bigger the ship the
better), but above that it becomes much more difficult.
If you read various books, I believe you'll find that @60' is considered
the maximum that waves can reach at sea. I feel the number is
considerably higher, but no where near 200'.
It's kinda like reporting roll angles with a "clinometer" .... "we were
rolling 40 deg by the clinometer" .... in truth, their roll angle was
closer to 20 deg.

Ok, good points, but I'm confused by this last exanmple.
