Of course, there's also reality. It's all a lot less romantic when the sea is having a snit, the temperature hovers at one extreme or the other, the gale warnings are flying, and the air is perfumed by rotting fish. Isolating this assault on the senses is the reasoning behind so many new superyachts with their sealed windows, their ever-present climate control, and their at-anchor stabilization systems. Alas, something's been lost in the process, and that's a sense of being at sea. On some yachts, the interior environment, and to some extent the outside environment, is so completely controlled that you have to pull aside the curtains to see if you're even moving. You might just as well fly to a five-star hotel and spend your time in the presidential suite.
