A man wearing a blue blazer with an official race badge pinned to the breast pocket had been peering through binoculars at the flat green expanse of the Pacific. He rubbed his eyes and squinted into the lenses again. In the distance thin white plumes were etched against the blue sky where it met the water. He lowered the binoculars, raised an aerosol canister with a plastic trumpet attached, and pressed the button three times.

Hawnk... hawnk... hawnk.

The klaxon's blaring squawk echoed across the water like the mating call of a monster gander. The flotilla took up the signal. A cacophony of bells, whistles, and horns filled the air and drowned out the cry of hungry gulls. Hundreds of spectators excitedly reached for their binoculars and cameras. Boats heeled dangerously as passengers shifted to one side. On the Nepenthe the guests wolfed down their food and poured from the salon sipping from glasses of bubbly. They shaded their eyes and looked off in the distance, where the feathery plumes were thickening into bantam rooster tails. Carried on the breeze was a sound like an angry swarm of bees.

In a circling helicopter a thousand feet above the Nepenthe, a sturdy Italian photographer named Carlo Pozzi tapped the pilot's shoulder and pointed to the northwest. The water was marked by parallel white streaks advancing as if plowed by a huge, invisible harrow. Pozzi checked his safety harness, stepped out onto a runner with one foot, and hefted a fifty-pound television camera onto his shoulder. Leaning with a practiced stance into the wind that buffeted his body, he brought the extraordinary power of his lens to bear on the advancing lines. He swept the camera from left to right, giving viewers around the world an overview of the dozen race boats cutting furrows in the sea. Then he zoomed in on a pair of boats leading the pack by a quarter of a mile.

The speeding craft skimmed the wave tops, their forty-foot hulls planing with elevated bows as if trying to escape the restraints of gravity. The lead boat was painted a bold firehouse red. Trailing by less than a hundred yards, the second boat sparkled like a gold nugget. The boats were more like star fighters than craft designed for travel over water. Their flat decks connected two knife-edged catamaran hulls called sponsons and aerodynamic wings over the engine compartments. Twin F-16-type canopies were set side-by-side two-thirds of the way back from the sharp-pointed double prows.

Squeezed into the red boat's right-hand canopy, his sun bronzed face fixed in a mask of determination, I Curt Austin braced himself as the eight-ton craft slammed against the concrete-hard water again and again. Unlike a land vehicle, the boat had no shock absorbers to cushion the jarring impact. Each jolt traveled through the one-piece Kevlar and carbon composite hull up through Austin's legs and rattled his teeth. Despite his broad shoulders, his muscular biceps, and the five-point harness system that strapped his two-hundred-pound frame in place, he felt like a basketball being dribbled down the court by Michael Jordan.
