The power of a large breaking wave is not to be under estimated.
Wow. A 45 footer! Wayne was it a rogue wave or could they have
detected it coming?

"Rogue Wave" is imprecise terminology which usually means a wave that
is much larger than others around it. All we know for sure is that
they were near a tricky ocean inlet, and inlets are a breeding ground
for breaking waves because of shallow water and currents. They
probably had little or no warning. Reported and forecasted wave
heights are an average, and from a statistical stand point it is
entirely possible to get waves that are 2 and 3 times larger than
average, sometimes more. Waves also dramatically increase in height
and steepness as they approach shallow water and/or an ebb current.
It is not height alone which capsizes boats but the steepness of the
leading edge. As steepness increases, the wave literally trips over
itself and starts to break. It has been calculated that any boat can
be capsized if the height of a breaking wave approaches a little more
than half the boats width (beam).
