I think the big difference is that this buoy was out in the open ocean - not surf. The study of open-ocean “rogue” waves is important to shipping, etc. Every once in a while one will catch a boat by surprise and sink it. Although I have no idea if this was one isolated monster wave - or was in the middle of a storm and was the tallest one.

You are precisly correct. When big waves hit the shallows they can become monster waves. What hit us in the middle of the North Sea was a monster wave a rogue wave it was. It was a least a 100 feet trough to crest.
