In time the yacht made its way out into the estuary of the Yangtze, only 
a few miles from the East China Sea at this point, miles wide, and much colder 
and rougher. Judge Fang and Dr. X repaired to a dining cabin belowdecks with 
panoramic windows that mostly just reflected back the light of the candles and 
lanterns around the table. Not long after they had taken their seats, the yacht 
accelerated powerfully, first shooting forward and then leaping up out of the 
water before resuming its steady, level motion. Judge Fang realized that the 
yacht was actually a hydrofoil, which had been merely idling along on her hull 
while they had enjoyed the city view but which had now climbed up out 
of the water.
