Mother Nature can be pretty unforgiving, and storms at sea are among the harshest of her displays of power. Everyone has heard of the Titanic, of course, but have you heard of the Brittanic? It's actually a sister ship to the Titanic that was built by the same company only a few years after the Titanic sank. It was meant to be a cruise ship as well (with more life boats, this time) but was turned into a hospital ship for the Navy during World War II. It was sunk by missile fire and most of the crew escaped.
