[camaraderie]

Dawg/Bubb...I don't know about the Maine stuff...want to read more on that. My initial reaction is that a tsunami type wave would have not even been noticed well out to sea and I can't sea storm driven waves doing the rapid rise and fall reported in Maine. I would thing the two are thus unrelated.
But I have read that a wave TWICE the size of prevailing conditions occurs once in every one thousand waves. So...if the waves are 30 feet with a period of 10 seconds, you will see a 60 foot wave once every 10,000 seconds...or about once every THREE HOURS...less if the period is shorter. Truly gigantic rogue waves are quite a bit rarer though more frequent than previously thought...but the idea of a 60 foot wave occurring once every 3 hours in a real storm at sea is pretty intimidating in and of itself.
