Back from Key West, the Conch Republic, where the captains who run the sunset sails thrill their predominantly Boomer fare with the knee-slapper, “Welcome to North Cuba!”, upon return in the darkness because for most of us land lubbers it’s more than a little disorienting out there, for an hour out of the sandbank and mangrove low-water keys, the Gulf Stream visible the night we see the sun sink into the horizon and the captain blows the conch so that his face glows purple in contrast to the blood-orange of the sunset, all aboard the AppleBone, as poet Billy Collins dubbed it, because it was a literary cruise, not like the Disney one, a floating theme park that moored near our oceanfront balcony, ESPN Sports Center on a giant screen topside blaring into the otherwise romantic night; shallow draught Caribbean port bruisers these beasts; how they get into the slips with water deep as elderly knickers is anybody’s guess, and a frightening thought that the town fathers have been considering allowing 10,000-passenger monsters into port (although the Italian cruise disaster may put an end to that . . .), which if that doesn’t kill whatever charm north to central Duval Street has left then I’m a monkey’s uncle, not to mention the safety of the cruise ships themselves, don’t begin to think that the capsizing of the Costa Concordia is an anomaly, the physics of these boats leaving no margin for error, turn away if you see the chalkboard math on the probability of it happening again, and especially in a place like Key West, where you do have to ask the question, “Well, how many people can drown in two feet of water?”
