Blue Mars - Kim Stanley Robinson [347]

They sailed out of the Florentine on a windy cloudless day, Ann at the rudder and Sax up in the starboard bow of the sleek new catamaran, making sure the anchor cat had secured the anchor; which reeked of anaerobic bottom mud, so much so that Sax got distracted and spent some time hanging over the rail looking at samples of the mud through his wristpad magnifying lens: a great quantity of dead algae and other bottom organisms. An interesting question whether or not this was typical of the North Sea’s bottom, or was restricted for some reason to the Chryse Gulf environs, or to the Florentine, or shallows more generally—
“Sax, get back here,” Ann called. “You’re the one who knows how to sail.”
“So I am.”
Though in truth the boat’s AI would do everything at the most general command; he could say for instance “Go to Rhodos,” and there would be nothing more to be done for the rest of the week. But he had grown fond of the feeling of a tiller under his hand. So he abandoned the anchor’s muck to another time, and made his way to the wide shallow cockpit suspended between the two narrow hulls.
“Da Vinci is about to go under the horizon, look.”
“So it is.”
The outer points of the crater rim were the only parts of Da Vinci Island still visible over the water, though they weren’t more than twenty kilometers away. There was an intimacy to a small globe. And the boat was very fast; it hydroplaned in any wind over fifty kilometers an hour, and the hulls had underwater outriggerkeels that extended and set in various dolphinlike shapes, which along with sliding counterbalance weights in the cross struts kept the windward hull in contact with the water, and the leeward hull from driving too far under. So in even moderate winds, like the one striking their unfurled mast sail now, the boat shoved up onto the water and skated over it like an iceboat over ice, moving at a speed just a few percent slower than the wind itself. Looking over the stern Sax could see that a very small percentage of the hulls were actually in contact with the water; it looked like the rudder and the outrigger-keels were the only things that kept them from taking flight. He saw the last bits of Da Vinci Island disappear, under a bouncing serrated horizon no more than four kilometers away from them. He glanced at Ann; she was clutching the rail, looking back at the brilliant white V-tapestries of their wake. Sax said, “Have you been at sea before?” meaning, entirely out of the sight of land.
“No.”
“Ah.”
They sailed on north, out into Chryse Gulf. Copernicus Island appeared over the water to their right, then Galileo Island behind it. Then both receded under the blue horizon again. The swells on the horizon were individually distinct, so that the horizon was not a straight blue line against the sky, but rather a shifting array of swell tops, one after another in swift succession. The groundswell was coming out of the north, almost directly ahead of them, so that looking to port or starboard the horizon line was particularly jagged, a wavy line of blue water against the blue sky, in a too-small circle surrounding the ship— as if the proper Terran distance to the horizon were stubbornly embedded in the brain’s optics, so that when they saw things clearly here, they would always appear to stand on a planet too small for them. Certainly there was a look of the most extreme discomfort on Ann’s face; she glared at the waves, groundswell after groundswell lifting the bow and then the stern. There was a cross chop nearly at right angles to the groundswell, pushed by the west wind and ruffling the bigger broader swells. Wavetank physics; one could see it all laid out; it reminded Sax of the physics
