We all know that large structures have to have some "give" in them to absorb stress… normally a very rigid structure (unless incredibly heavy) won’t survive. I’ve certainly seen aircraft wings "flapping" in turbulence, but this video shows a large container ship flexing the best I’ve ever seen. A couple of segments during the video show a long shot down an internal companionway… watch it move 🙂

Also shows just how I DON’T want to be out in ocean weather in the types of boats I’m dealing with right now.
