Shallows and Sandbars

The echo sounder gave a shrill, rhythmic chirp that climbed in pitch with every second.

On the console screen, the digital depth readout flickered from two point four down to two point three meters. A red warning banner flashed across the sonar raster, painting Captain Sander Klaaskerk’s hard cheekbones in crimson light.

"We have thirty centimeters of clearance under the keel," Liselotte said, bracing her palms against the wooden chart table. "Less if the riverbed rises ahead of the limestone bluff."

"Twenty-five," Sander corrected without looking away from the dark water beyond the forward glass. His large hands held the bronze helm steady, knuckles pale under the dim glow of the instruments. "The stern squats another five centimeters when the propeller bites."

Behind them, the wheelhouse door swung open with a rattle of brass hardware. Joost scrambled inside, his yellow foul-weather jacket buttoned crookedly up to his chin. He clutched an aluminum sounding pole in both work gloves as though he intended to duel the river.

"Captain, the fairway buoys look closer than usual," Joost blurted, adjusting his thick workshop goggles with a wet sleeve. "I can hear gravel scraping along the outer bank. Are we going to beach her?"

"We are not beaching anything," Sander said in a low, level baritone. "Joost, take the forward windlass station. Stand by the port anchor brake. Do not release the drum until I give the blast."

"Port anchor, yes, Captain!" Joost spun on his heels, squeaked against the rubber deck runner, and ducked back out into the cool night air.

Liselotte pulled the laminated hydrographic sector chart across the mahogany desk, her fingertips tracing the tight blue contour lines south of the limestone bend. "The main shipping lane is choked with silt, but look here. Two hundred meters past the old quarry dock, the current gouged a scour pool along the eastern bluff. It drops to four meters."

Sander glanced down at the chart, his shoulder brushing hers in the narrow space between the helm and the console. The clean, sharp scent of cold river air and engine oil clung to his woolen sweater. "The approach to that pocket narrows to ten meters across. If we slide off by a foot, we ground on broken limestone."

"The bottom staves of my oak casks can take a gentle grounding far better than dead stillness," she said, meeting his gray eyes. "The wild yeast needs agitation. If the river halts completely, the sediment drops to the floor and chokes out the ferment."

"I am not risking my hull on a guess, Lotte."

"It isn't a guess." She tapped the surveyor's mark from the provincial water authority. "The limestone bluff deflects the main flow eastward. The water has nowhere else to go. Steer two points off the red beacon, follow the foam line, and the depth holds."

Sander held her gaze for two long seconds. The rigid set of his jaw softened just enough for a faint crease to appear beside his mouth. "You trust an eight-year-old surveyor's chart over my sounder?"

"I trust the way water carves stone."

He pulled the throttle lever back a notch, dropping the diesel engine's hum to a deep, vibrating rumble. "Hold on to the console rail."

Liselotte gripped the polished brass rail as Sander eased the heavy wooden helm to starboard. The long steel bow of the Vrouwe Johanna swung slowly across the black surface of the river. Outside, the sheer white walls of the limestone bluffs rose like pale ghosts out of the dark, their craggy faces throwing back the low murmur of the exhaust.

The echo sounder shrieked. Two point zero meters. One point nine.

A dull, shuddering scrape traveled up through the barge's steel frames, vibrating right into the soles of Liselotte's boots. It was not a violent impact, but the heavy, dragging friction of river gravel kissing the flat keel plate.

Her heart leaped into her throat.

Sander did not flinch. He did not curse. With swift, deliberate precision, he kicked the throttle ahead with his left hand while spinning the helm hard to port. The big diesel roared, throwing a white plume of churning water against the dark riverbank. The hull groaned, slid free of the gravel bar with a wet hiss, and glided forward into silky, unbroken black current.

The digital depth sounder blinked, chimed once, and reset: three point two meters. Then three point eight. Four point one.

"Scour pool," Sander said quietly.

He throttled the diesel back to neutral and reached for the horn lanyard, pulling two sharp blasts that echoed off the rock cliffs.

Forward on the bow, a loud metallic clatter shattered the night. Joost tripped the windlass brake. The heavy steel anchor chain roared through the hawsehole with a shower of sparks, plunging into the deep water. The heavy links snapped taut with a ringing shudder that shook the deck timbers. Moments later, the stern kedge dropped with a dull splash, locking the vessel in place against the slow eddy.

Sander reached for the ignition panel and cut the fuel injector pump.

The giant engine gave one last shuddering cough and died.

A sudden, total silence crashed over the wheelhouse.

Liselotte let go of the rail, her fingers stiff from tension. Without the relentless thrum of the engine and the rolling motion of the hull against the current, the river valley felt unnervingly still. The gentle sway that had kept her cider bubbling and rolling in the hold had vanished. The dark water lapped softly against the hull plates, but inside the ship, nothing moved.

"She's resting in four meters of clean water," Sander said, wiping his palms on a cotton rag before setting it neatly beside the throttle. "No damage to the plates. The anchors will hold us until the weir gates open at dawn."

Liselotte walked to the forward window, staring at the motionless black surface of the Maas. Her voice came out tight. "Twelve hours of dead calm. The yeast will drop out of suspension. The sugars on top will oxidize while the bottom turns bitter."

Heavy footsteps crossed the wheelhouse floorboards. Sander stopped beside her, his tall frame blocking the cold draft from the doorway. He did not touch her, but the steady warmth radiating from his shoulder was unmistakable.

"You brought two manual wooden rudders and paddle oars for the open vats, didn't you?" he asked quietly.

She glanced up at him in surprise. "Those are for cellar work at the orchard."

"Then we use them in the hold tonight," Sander said. His deep voice carried no mockery, only the calm certainty of a man used to working through the dark. "Joost and I take turns on the deck watch. Between rounds, I'll go below and help you stir every single cask by hand."

Liselotte stared at him, the tension in her chest easing into something warm and unsteady. "You're willing to shovel cider lees at two in the morning?"

Sander looked down at her, a rare, faint smile touching the corner of his lips under the green running light. "I told you at the quay in Maastricht: your cargo stays alive as long as it's aboard my ship."

He reached out and closed the brass latch of the starboard window against the night breeze, his sleeve brushing her arm as he secured them in the quiet dark.
