I'd draw your attention to the second photo of the Nedlloyd Barcelona. Those containers are eight feet tall each, the photo was shot from the bridge deck, and I have been fortunate to have never been at such an angle to seas. The only way that you can get the photo angle that you see is in truly large swells.
You'll notice that in the heavy weather damage photos that substantial damage occured aft. Contrary to popular belief, bow to the seas is not the point of most relief in heavy weather. Due to high winds, and the large sail area of the vessels, it may be impossible to maintain steerage way. In the really nasty stuff, you're forced to lay with the seas on the quarter. You'll roll, boy will you roll, and quite deeply. Attempting to meet such seas bow on is to break the ship, if you don't stove her in first. Eventually, with the seas on the quarter, you'll roll deeply and some containers will take a boarding sea. Once one of the lower ones is damaged the uppers will exacerbate the damage.
Notice how little damage to the ship herself? Containers are relatively weak.
