Wow. Hope to never run into anything like this while cruising on the Maine
coast (knocks on wood). Sounds like it would have been (at best) VERY SCARY to have been headed in or out of the harbor at this time.
Boothbay Harbor, Maine
"Dockworker Marcy Ingall saw a giant wave in the distance last Tuesday afternoon and stopped in her tracks. It was an hour before low tide in Maine's Boothbay Harbor, yet without warning, the muddy harbor floor suddenly filled with rushing, swirling water
In 15 minutes, the water
rose 12 feet, then receded. And then it happened again. It occurred three times, she said, each time ripping apart docks and splitting wooden pilings."
