Did you pay attention to the lifeboat drills, or, like most people stand there day dreaming about the crabcakes and mellon balls? Did you explore alternate routes to your assigned lifeboat station? The dangers of crowd behavior didn't stay on land. Do you have some quickly grabbed and donned clothing ? Some of the survivors of the General Belgrano made it into liferafts only to die of hypothermia. A watch cap, gloves, warm pants and easilly donned sweater or jacket should be mandatory for everyone. A whistle and mirror, LED light and bit of high energy food in a pocket wouldn't hurt. Just because there is heavy weather doesn't mean you are alone. Emergency agencies will contact merchant shipping and naval vessels in your vicinity. I'm trying to figure out what weather grounds SAR units. A C 130 will probably be circling overhead in weather a seagull would avoid.
