Sounding the Horn in a Gale

The outer spillway race was running thirty knots of white froth beneath a Force 8 gale, but Storm-Warden Vencel Csortos still reached for the brass pneumatic whistle lanyard.

"Warden, she is pulling sixteen degrees off our port bow and skipping the chop like a skipped flat pebble," Sub-Warden Tivadar shouted over the howl of the salt wind, bracing both boots against the bridge console of Holló-04. "If you sound the whistle, you will only give her pilot our closing vector!"

"Article Nineteen of the Continental Navigation Charter requires two short blasts before any overtaking maneuver in restricted outer raceways," Vencel said. His hand pulled down on the cord.

The cutter's twin steam horns shrieked into the squall. Two clean, pressurized blasts cut through the roar of three-story breaker waves and the screaming whine of twin supercharged hydro-turbines. High above the wheelhouse, the lone green masthead lantern threw a sharp emerald circle across the flying spray.

A quarter-mile ahead, the corsair skimmer Csóka bucked through the trough of a gray swell. The outlaw craft was running on extended titanium-composite hydrofoils, lifted clear of the brutal drag of the chop, twin rooster tails of foam boiling thirty paces into the storm. But her balance was ragged. Her starboard ski had taken heavy scouring along the lock sills, leaving her riding slightly askew, throwing a jagged feather of spray that betrayed every adjustment of her helm.

"Range, one hundred and eighty paces," Tivadar called out, his knuckles white against the throttle gate. "Her draft is shallow, Warden. If she clears the shoals of the Western Breakwater, her foils will carry her into the flooded limestone shallows where our keel cannot follow."

"Advance turbine pressure to maximum emergency rating," Vencel ordered. "Set the helm three degrees starboard to cut across her wake."

Holló-04 surged forward. Her reinforced ice-class prow knifed into the shoulder of a collapsing comber, drowning the forward observation deck in three tons of green water before the automated scuppers spewed the brine back into the dark. Spray hammered Vencel’s heavy gray oilskin coat, stinging his cheeks with frozen salt.

Through the rain-streaked windscreen, movement flared on the corsair's aft deck.

A figure emerged from the low hatchway of Csóka, hauling herself onto the stern transom beside the roaring engine cowlings. Dark braided hair whipped across a pale face. Even through the curtain of spray, Vencel recognized the silver-ringed injector harness strapped around her throat. Boróka Nyáry had hooked her boots into the deck straps and was bracing herself against the skimmer's roll.

She raised one hand, thumb pressed to the release valve of a potassium-saline flask at her hip, and spit the wash into the wind. Then she clamped both palms against the reinforced rubber housing of her collar.

"Acoustic flare on their stern!" Tivadar yelled, ducking instinctively behind the bulletproof plinth of the helm. "She's spooling her throat coils!"

Vencel did not duck. He planted his boots directly on the shuddering steel deck plates, stepped out onto the open bridge wing, and raised both arms into the gale.

The air around him hummed. Under the discipline of his training, the cold nitrogen and oxygen molecules between the two speeding hulls began to resist the wind. He measured the roll of the cutter, the interval of the incoming rollers, and the exact distance closing between the two vessels. Twenty-eight paces. Within his envelope.

Across the froth, Boróka tilted her head back. Her throat collar flared with an amber discharge arc as the injector delivered a jolt of electrolyte fluid into her vocal nerves. Her mouth opened.

She did not scream. She sang a single, razor-thin harmonic note that sliced through the thunder of the gale like a scalpel through sailcloth.

The sea between them split. The water did not merely splash; the acoustic shockwave flashed along the surface as a line of cavitating vacuum pockets, vaporizing the crests of three intervening waves into instantaneous steam. The concussive front barreled straight toward the bridge of Holló-04, carrying force enough to buckle hull framing and rupture human eardrums across a twenty-yard radius.

Vencel clenched his fists and thrust his palms down at a thirty-degree angle.

He compressed the atmosphere into an invisible pane of solid kinetic glass, eight inches thick and fifteen paces wide, angled like a submerged wedge directly into the path of the incoming sonic pulse.

The collision tore a sharp crack from the empty air. The acoustic wave slammed into the hardened density barrier with the screech of dry metal grinding against a lathe. White vapor erupted where the sound energy struck the molecular wall, the transferred kinetic momentum driving a hot spike of muscular pain straight up Vencel’s forearms and into his collarbones. Blood surged against his temples, hot and sharp, but his boots did not slip an inch across the wet steel.

He twisted his wrists, tilting the barrier's plane.

Instead of shattering against his chest, the deflected shockwave rebounded downward, funneling into the boiling trough beneath Csóka's port flank.

The redirected acoustic pressure detonated against the sea surface directly beneath the pirate craft. The hydraulic hammer smashed into the skimmer's port hydrofoil strut. Metal groaned in agony. With a sharp snap that sounded like an artillery breech opening, the hydrofoil's shear-pins gave way.

The port foil whipped free into the dark water. Deprived of lift on her outer beam, Csóka dropped violently off her plane. Her flat-bottomed aluminum hull slapped into the sea trough with a tremendous crash of displaced spray, spinning forty degrees across her line of advance as her rudder fought the sudden drag. Her hydro-turbine sputtered, gagging on aerated foam.

"Target has lost foil balance!" Tivadar roared from the bridge, his voice cracking with disbelief. "She's dead in the trough, Warden! We have her flank!"

"Cut throttle to half," Vencel commanded, lowering his shaking hands to grip the cold bridge railing. His chest burned with metabolic exhaustion, but his breathing remained strictly level. "Swing our bow ten degrees port. Sound three short whistle blasts to signal engines going astern. Lay us alongside her starboard quarter and prepare the magnetic grapples."

Tivadar pulled the whistle cord again. Three sharp blasts barked into the wind. Holló-04 swept around the shuddering pirate craft, her high steel bow pushing a wall of foam that corralled the wallowing skimmer against the cutter's reinforced rub-rail.

On the stern deck of Csóka, Boróka had been thrown against the low cockpit coaming by the crash. She was back on her feet within two seconds, wiping brackish water from her eyes with the back of an oil-stained leather glove. Her face was flushed, her chest heaving as she coughed against the laryngeal strain, but her fingers were already reaching toward the pry-bar lashed to the engine box.

"Heave lines!" Vencel called down to his tactical deckhands, stepping to the bridge rail. "Stand down, Captain Nyáry! Your vessel has suffered structural failure in restricted waters. Under Section Four of the Continental Maritime Charter, you are subject to immediate boarding and search!"

Boróka leaned against the cockpit comb, coughing once into her collar before lifting her chin to glare up at the cutter's bridge. "You blew the whistle," she rasped, her voice rough as broken shale from the acoustic discharge. "We were half a mile from the breakers, you nearly took my foil through my own cockpit, and you blew the damn whistle."

"Navigation regulations apply in all weather conditions," Vencel said, unholstering his sidearm and keeping the barrel pointed at the wet deck plates between them. "Secure your engines and step away from the hatch."

Before she could speak again, the ocean beneath them stopped moving.

The wind still howled through the stays, and the rain still pelted the iron plating, but the swell beneath both keels seemed to lose its rhythm for a split second.

Then it struck.

A low, metallic, sub-audible sonar ping rose out of the abyssal trench thirty fathoms below. It was not a mechanical pulse from an Authority transponder, nor the dull thud of shifting masonry. The sound tore through the water with colossal hydraulic amplitude, vibrating through the double-bottom steel of Holló-04 and the light alloy ribs of Csóka simultaneously.

The shock shivered through the soles of Vencel’s boots, rattling the rivets in the bridge deck and humming through the fillings in his jaw. In the wheelhouse behind Vencel, Tivadar pulled off his acoustic headset, his face pale under the green binnacle glow. "That was no seismic echo, Warden. It's an active bathymetric sweep. Sector Four's automated strike array just acquired Lock Seventeen's bedrock."

Across the churning narrow gap between their hulls, Boróka let her hand fall from the engine box. She leaned against her buckled coaming, looking up at the high gray prow of the cutter.

"You have forty seconds before that guidance loop arms its detonators, Warden," she said, her strained voice cutting flat and dry through the wind. "You can haul me to the brig in iron cuffs, or you can step down onto my deck and read the bathymetric cylinder."

Vencel looked at the outlaw captain, then clicked the safety catch on his service pistol and slid the weapon back into its holster. The Continental Navigation Charter had no provisions for an automated treason strike, but Subsection Nine permitted mutual salvage protocols during imminent navigational ruin.

"Sub-Warden," Vencel called up to the wheelhouse, his voice steady over the surge. "Belay the arrest irons. Secure the magnetic towing clamps and bring the diagnostic bridge harness."
