The Navigator

an hour, the high-wing aircraft would cover a thirty-thousand-square-mile expanse of ocean before its patrol ended.

The Coast Guardsman at the plane’s radar console was daydreaming about his upcoming date with a young Newfoundland woman. He was working on a plan to get her into bed when he saw the suspicious blip on the plane’s radar screen.

Training set in. The radarman put aside his prurient thoughts and focused on the radar screen. The four- engine turboprop carried radar that looked forward and sideways. The side-looking radar, or SLR, had picked up the large object in the water around twenty miles to the north.

Iceberg detection had come a long way since 1912, when the ice patrol was created to prevent a repeat of the Titanic disaster. Despite the technological advances, identification is considered more of an art than a science.

The radarman tried to decide whether the object was an iceberg or an anchored fishing boat. A smooth- edged moving target would denote a vessel. The blip was almost stationary and showed no sign of a wake. His practiced eye picked out the radar shadow, where there was no radar return on the far side of the target, a phenomenon that indicated that the target was taller than a ship.

Iceberg.

He notified the cockpit of the sighting and its location, and the plane veered off on a northerly course change.

The fog hanging over the ocean surface prevented visual identification until the very last minute. The plane dropped down until it was several hundred feet above the water. The mists cleared to reveal an iceberg with a tall, narrow pinnacle at one end. Then the fog closed in again. The brief glimpse was all that was needed.

The plane sent the iceberg data to the ice patrol’s operations center in Groton, Connecticut. There, a computer figured out the iceberg’s probable drift. A warning was broadcast over the radio as a bulletin to the maritime community. The report was picked up by a Provincial Airlines Beech Super King that had been patrolling the Grand Banks under contract to the offshore drilling industry.

The two-engine plane homed in on the broadcast coordinates. The fog was clearing, and the plane found its target with no trouble. After making a couple of low-altitude passes, the plane radioed a confirmation of the sighting to the drilling platforms and vessels in the vicinity.

THE Leif Eriksson had been cruising at a lazy meander when the vessel received the urgent message. Immediately, the ship’s twin ten-thousand-horsepower diesels flexed their muscles in a noisy display of power. Leaving a creamy wake in the gray seas, the vessel raced off like a motorcycle cop chasing a speeder.

Austin had been in the bridge poring over a chart with Zavala when the report came on over the radio’s speaker.

“Our missing Moby?” Austin asked the captain.

“Could be,” Dawe said. “She fits the description. We should know soon enough.”

Dawe ordered the ship’s engine room to cut speed. Cottony wisps of fog were curling around the ship’s plunging bow. Within minutes, a colorless miasma wrapped the ship like a wet dishcloth. Visibility was reduced to spitting distance. The ship groped its way along relying entirely on its electronic eyes.

The captain kept close tabs on the radar screen and called out commands from time to time for the helmsman to adjust course. The ship was moving at a crawl, and the tension on the bridge was thicker than clam chowder. The ship was traveling through the haunted waters near the grave of the Titanic. Even with electronics that could pinpoint a toy boat in a rain puddle, ship collisions with ice were not uncommon, and sometimes fatal.

The captain emitted a cryptic grunt and looked up from the radar screen.

He grinned and said, “Did I ever tell you what a Newfie uses for mosquito repellant?”

“A shotgun,” Zavala said.

“The mosquito will crash when you shoot out its landing lights,” Austin added.

“Guess you heard that one. Don’t worry; we’ll make Newfies out of you yet.”

With the tension broken, the captain turned his attention back to the radar screen. “Fog’s let up a bit. Keep an eye out. Any second now.”

Austin scanned the grayness. “We’ve got company,” he said, breaking the cathedral quietness on the bridge.

The ghostly outlines of an enormous iceberg loomed ahead like something in a dream. Within seconds, the mountain of ice became more solid and less spectral. The berg angled up from one end to a lofty pinnacle that rose as high as a fifteen-story building. A stray shaft of sunlight had penetrated the fog. Under the glare of the heavenly spotlight, the berg glowed with a bone white sheen except for the sky blue crevasses where the refrozen meltwaters were free of bubbles that reflected white light.

The captain slapped Austin and Zavala on the back. “Grab your harpoons, boys. We’ve found Moby-Berg.” He gazed in rapture at the enormous berg. “Real pretty, eh?”

“Quite the little ice cube,” Austin said. “And we’re only seeing about an eighth of the berg above water.”

“There’s must be enough ice there for a billion margaritas,” Zavala said with undisguised awe.

Dawe said, “She’s a castle berg. Like the one that sunk the Titanic. The average berg in this neighborhood runs a couple of hundred thousand tons and maybe two hundred feet in length. This one is around three hundred feet plus and maybe five hundred thousand tons. The Titanic iceberg was only around two hundred fifty thousand tons.”

The captain ordered the helmsman to circle the berg, coming no closer than one hundred feet. “We’ve got to be extra careful,” he explained.

“Those projections poking from the water look as if they could scrape the barnacles off our hull,” Austin said.

The captain kept a level gaze on the berg. “It’s the obstructions we can’t see that I worry about. Those blue cracks are weak spots. A gigantic piece of ice could break off at any time and the splash alone could sink us.” Dawe flashed a quick grin. “Still glad you hooked a ride with us?”

Nodding in agreement, Austin tried to absorb the deadly beauty of the majestic ice mountain.

Zavala had shed all his reservations about the trip and stared spellbound at the huge berg. “Fantastic!” he said.

“Glad to hear that, my friends, because his baby belongs to you. A NUMA ship helped me out of a jam some years ago. This is my way of paying you back. The ship’s owners say liability won’t be a problem as long as you sign on as temporary members of the crew, which you’ve already done. You showed yourself to be naturals rounding up bergy bits.”

Dawe had let his guests lend a hand lassoing the smaller bergs, loosely misnamed after the fast-food specialty. Their teamwork and the way they quickly picked up the technique had impressed him.

“Those bergy bits were the size of houses,” Austin said. “That thing out there is as big as the Watergate complex.”

“The principle’s the same. Spot ’em. Encircle ’em, rope ’em, and tow ’em. I’ll be watching over your shoulder in case you get into trouble. Get into your foul weather gear. Meet you on deck.”

Austin and Zavala grinned like kids getting their first two-wheeled bike. They thanked the captain and headed to their cabin. They pulled on extra layers of warm clothing and slipped into full suits of bright orange foul weather gear. By the time they stepped out onto the open, the wind had picked up. The patched surface of the sea was as rough as alligator skin.

The captain watched closely as the two men worked with the crew to shackle together twelve-hundred-foot- long sections of eight-inch-thick polypropylene towrope. The towrope was attached to a cylindrical bollard on the aft deck and was paid out through a wide opening in the stern rail. An orange buoy was attached to the free-floating end. Austin used a portable radio to contact the bridge to say all was ready.

The ship moved in a big circle, staying about two hundred feet away from the berg, stopping to allow the crew to shackle sections to the towline.

When the Eriksson came back to its starting point, a crewman grappled the buoy end floating in the water and hauled it on deck. Austin directed the seamen to attach a wire towline to keep the
