"Hurricane-force gusts can knock the copter side to side, up and down. The sea can rise and fall the height of a three-story building in a minute."
Make that "in a second."
The worst I ever saw on my sailboat was 20 feet, from 3 directions. It was scary enough, but it was in Mexico, daylight and 80 degrees water and air temp.
These guys are amazing!

I have lost several friends crab fishing out there. The boats ice up and capsize without the time to get a mayday off.
