Boats and computers . Economically speaking, none of these things have an OFF switch. Clock is always ticking. Except that a boat is a couple hundred times larger than a computer and you can't just stuff it in the closet and forget about it. Much as we might like at times.
Boats are like having a baby.
They make constant demands on your time and wallet. I won't even mention labor pains. The finance company and the marina sometimes call to remind you of this unpleasantness. At least it can go in the closet. Nobody ever puts junk computers in the trash.
