The Jabuticaba bobs gently on the sea, a few hundred metres off Morjim beach in northern Goa. On board, I curl my toes happily against the teak deck and look at the nearby stretch of sand. It&rsquos called Turtle Beach, and I wonder idly about the immensely hard work female turtles must do to lay eggs in their nesting sites. There is no time and place quite as nice as sunset on a beautiful yacht for the utterly idle contemplation of the industriousness of others.
