Easily spotted, the Megayacht is more than 100 feet long and owned by people with more money than God. Generally staffed by good-looking androids in matching T-shirts, the Megayyacht's hospitality depends entirely on who's at home. Sidle up in your dinghy and ask discreetly, "Are your owners on board?" If not, the androids turn into good-natured Australians tossing ice-cold beers from their walk-in refrigerator. Otherwise, you'd better move on before someone makes you polish the stanchions.
A friend of mine actually hitched from here to south florida and found a fellow who was going to Amsterdam. No ID, no money, barely any clothes. He is still over there, and very happy. To own an oceangoing vessel is ungodly expensive, but retired folks are sometimes just cool as hell.
