Follow the Container has an amazing video from You Tube onboard a containership.
It is filmed during a heavy storm. Watching this, one realizes how it is containers get washed overboard, as well as the perils of sailing.
I remember a guy I use to work with, Rainer, sailed on a tankers. He said they use to tie ropes around themselves during storms.
Enjoy viewing, but honestly, I almost got sea sick watching this.
