An older Bowditch claims a reliably reported 112 footer. This may have
been updated, now that we have the various satellites which can measure
more accurately, as Calif B has stated.

I personally can't attest to wave heights, but there is evidence for
100' waves having existed.

Having said that (and I've looked but can't find a source on the web,
I'll have to look for another one) I read somewhere that the
theoretical height limit for a "rouge" wave is 178' - has to do with
the speed, weight of the water, etc. After a certain point, the water
can't support it'self.
