Imagine, for a moment, that you are aboard a 56 metre luxury yacht anchored off Sicily. It is before dawn, there's some wind but the crew aren't worried, and you're coming up to take a look around. Suddenly, the yacht is knocked about as all the windows explode around you. Confused, startled, and scared, you run for a muster station, managing to get aboard a life raft moments before the yacht disappears beneath the waves. The whole event took longer to write up than it took to happen.
