Derelict ships: the vessel sailed on after the last human decision.

In maritime use, a derelict is a vessel left without care while still afloat or aground. It needs no phantom and no table laid for a meal. Its real power comes from two timelines parting: the human record stops at a call, a frame of film or a log entry, while wind, current and sea ice continue to write positions for the ship.

A boarding party therefore meets the vessel after the event, not the vessel at the instant of crisis. Gear has shifted, sails may have torn, flooding may have changed and current may have carried the hull hundreds of miles. Every object can be genuine without still belonging to its original moment. The investigator has to walk backward through this moving scene toward the last decision made on deck.

Mary Celeste left New York for Genoa on 7 November 1872. Aboard were Captain Benjamin Briggs, his wife Sarah, their two-year-old daughter Sophia and seven crew; the hold carried 1,701 barrels of industrial alcohol. On the morning of 25 November, the log slate placed the ship near Santa Maria in the Azores. Human notation then stopped. Over the following ten days, the ship crossed roughly four hundred miles of ocean.

On 5 December, Dei Gratia found her yawing across the sea. When Oliver Deveau boarded, the ship's boat was gone, together with the sextant, chronometer, navigation book and vessel papers. One pump had been taken apart, a sounding rod lay nearby, hatches were off and water was aboard. Personal possessions and almost all the cargo remained. The things removed—boat, instruments and papers—look less like disappearance than a hurried, deliberate departure.

GIBRALTAR · SWORN EVIDENCE · 1872TRANSCRIPT ↗

The galley was in a bad state, the stove displaced and utensils scattered. The whole ship was thoroughly wet.

That three salvors later sailed Mary Celeste to Gibraltar does not mean Briggs had seen the same safe ship when he left. A modern reconstruction reported by Smithsonian offers one plausible chain: heavy weather, an increasingly wrong position and a fouled or failing pump may have left the captain unable to judge water in the hold. When Santa Maria finally appeared, he may have treated landfall as the one opportunity to wait in the boat. If its line parted, the faster hull would sail away without them.

The Gibraltar salvage court found no evidence sufficient to establish violence. Sworn evidence described a disordered galley, a displaced stove, scattered utensils and wet accommodation. The steaming tea and half-eaten breakfast arrived in later retellings. In 1884, Arthur Conan Doyle changed the name to Marie Celeste and invented a sole survivor. Reality left a sounding rod on deck; fiction furnished an empty dining room that would wait forever.

THE WASHINGTON HERALD · 03 FEB 1921LIBRARY OF CONGRESS ↗

Like a ‘Flying Dutchman,’ Deering loomed through the mist, all sails set, but unmanned.

Carroll A. Deering was returning from Rio de Janeiro in ballast by way of Barbados. On 29 January 1921, as she passed the Cape Lookout lightship, a man who did not appear to be the captain hailed that both anchors were lost and asked that the owner be notified. Two days later the five-masted schooner ran onto Diamond Shoals under full sail. Heavy weather delayed the Coast Guard until 4 February; only three starving cats remained aboard.

The log, navigation equipment, personal effects, two main anchors, motorboat and dory were gone; food stood in preparation in the galley. Five federal departments investigated while newspapers offered pirates, mutiny, rum-running and Soviet agents. A message in a bottle appeared to confirm an attack, until its finder, Christopher Columbus Gray, confessed to forging it. The Hoover files preserve correspondence, reports and photographs—and an uncomfortable fact: a dossier may grow while its evidence does not.

STATE CORONER · VIDEO RECORD · 10:05FINDINGS · P.9 ↗

The sea is choppy with occasional whitecaps. A squall can be seen ahead. None of the men is wearing a life jacket.

Kaz II was a 10.6-metre catamaran. On the morning of 15 April 2007, Derek Batten, Peter Tunstead and James Tunstead departed Airlie Beach in Queensland. At 10:05 a.m., James filmed the last known scene: Batten at the helm, Peter fishing from the port stern steps, a blue mug beside the wheel. Safety wires to the low stern platforms were open on both sides, a long white rope trailed astern, whitecaps crossed the sea, a squall stood ahead and none of the men wore a life jacket.

The recording gives Kaz II something no nineteenth-century file possesses: a whole deck less than an hour before the likely accident. The coroner reconstructed the most plausible sequence. One brother may have fallen while retrieving fishing line from the rudder and the other gone to help; Batten started the engine and moved to lower sail before turning back, where an uncontrolled gybe could have swept him overboard. No monumental wave was required—only three linked actions, and the entire human timeline ended within minutes.

No conscious evasive action helped the vessel avoid the reefs; chance, shallow draught and tide carried it over.

On 17 April, reef fishermen watched Kaz II pass through channels and assumed she was crewed because she appeared to navigate. GPS data later showed that shallow draught, tide and chance alone had carried her across the reefs. A surveillance aircraft found her about eighty nautical miles offshore on 18 April. The next afternoon rescuer Corrie Benson was lowered into the sea and had to swim hard toward the yawing boat, where trailing fishing line caught him at the stern.

Benson boarded to find the engine idling in neutral, a 15 April newspaper undisturbed on the table, the blue mug upright aft, orderly cabins and all life jackets aboard. Headlines made the scene look like a weekend still in progress. The official inquiry instead connected cup, line, open safety wires, raised swim ladder, torn headsail and GPS track into a rapidly unfolding man-overboard accident. The boat had not mysteriously taken three men. It had simply failed to stop.

ISOBEL WYLIE HUTCHISON'S PARTY · 1933MANITOBA MUSEUM ↗

She was hurrying north in her private ice pan.

Baychimo was a steel steamer built in 1914 and later bought by the Hudson's Bay Company to supply Arctic posts and carry furs. In October 1931, ice trapped her near Point Barrow. Some people evacuated while a remaining party built winter quarters ashore and cleared ice from the rudder each day. After a blizzard on 26 November, the ship vanished. The crew assumed she had sunk until an Inuk hunter reported her in ice roughly seventy-two kilometres away.

Captain Cornwell returned, removed a large cargo of furs and abandoned the damaged ship for the last time. Sea ice turned her into a moving island. In 1933, Indigenous Alaskans boarding her were trapped for ten days; that summer botanist Isobel Wylie Hutchison's party saw her ‘hurrying north in her private ice pan.’ A salvage attempt followed in 1939. Hudson's Bay Company Archives record the last sighting in 1969—thirty-eight years after abandonment. The human file was closed; the hull refused to sign its own ending.

The four vessels retained four forms of motion. Mary Celeste had sails, rudder surface and days of wind, and could proceed like an uncrewed but roughly balanced machine. Diamond Shoals stopped Deering. Kaz II's engine, sails, shallow draught and reef tide created the appearance of deliberate pilotage. Baychimo surrendered agency most completely: frozen into a floe, she travelled wherever the ice travelled.

We read motion as a trace of intention and instinctively search for a helmsman. Motion at sea does not require a story. Wind pressure, current, buoyancy, rudder angle, waves and ice drift can carry an object across coordinates without a person aboard. That calm physical continuation makes a finished disaster look like a voyage still happening.

Mary Celeste reached Gibraltar, Deering was dynamited as a hazard, Kaz II was towed to Townsville and Baychimo likely rests beneath the Beaufort Sea. Each hull acquired an ending. The water last seen by the missing people never entered the archive. Investigation can discard some stories, reconstruct actions from film and objects, and mark the border of inference honestly. It cannot summon a vanished instant.

This is the derelict's particular epic scale: not a monster, but the proportion between one small human act and oceanic time. Someone unclips a safety wire, takes up a sextant or steps off an icebound deck; the vessel continues for ten days, three days or thirty-eight years. The ship returns. The decision does not. Every later boarding takes place on the far side of that break.
