The Disappearance of the crew of the High Aim 6 (Taiwanese ship): Unraveling the Mystery at Sea
The crew of the High Aim 6 vanished without a trace, leaving behind an abandoned vessel and no clear explanation for their disappearance. In early 2003, the Taiwanese fishing boat was found drifting off the coast of Australia, fully stocked and in apparently seaworthy condition, but with its entire crew missing. There were no obvious signs of struggle, distress, or violence aboard the ship.
Investigators searched for clues but could not determine why the crew deserted the ship or what ultimately happened to them. Theories ranged from mutiny to piracy, yet none could be conclusively proven. The case remains unsolved, puzzling maritime experts and keeping the fate of the High Aim 6's crew shrouded in mystery.
Background of the High Aim 6
High Aim 6 was a Taiwanese fishing vessel that became the center of an international maritime mystery after its crew vanished in 2003. Details about its specifications, management, and the individuals who served onboard provide crucial context for understanding the circumstances of its disappearance.
Vessel Specifications
High Aim 6 was a longline fishing boat registered in Taiwan. The vessel measured approximately 20 meters in length and was designed for extended fishing voyages in open waters. Its build and equipment allowed it to operate for weeks at sea, with storage facilities for a significant catch.
The boat was powered by a diesel engine and had standard navigational tools for its class and era. Safety features included liferafts and emergency supplies, reflecting industry norms for international fishing trips.
High Aim 6 was identifiable by its registration number and markings in Chinese characters on the hull. The ship was considered seaworthy at the time of its last voyage, showing no signs of major mechanical issues before it was found adrift.
Ownership and Operation
The High Aim 6 was owned by a Taiwanese fishing company and registered in Taiwan. The vessel was operated from Taiwan, with direct oversight from the company based in the port city of Tungkang.
Management of crew recruitment and operations involved both local agents in Taiwan and partnerships with foreign labor agencies. The company supplied provisions, fuel, and fishing gear, maintaining regular contact with the captain using radio communication.
Operational records indicated the vessel departed Taiwan on October 31, 2002. It later sailed to Indonesia, where additional crew joined. Ownership remained constant throughout, with company records confirming proper registration until the ship was discovered abandoned in early 2003.
Crew Members and Nationalities
The crew of the High Aim 6 consisted of a Taiwanese captain, a chief engineer also from Taiwan, and eight Indonesian fishermen. The selection reflected typical manning practices for Taiwanese fishing fleets, which often combined local leadership with experienced foreign workers for deck and engine roles.
Crew lists were maintained in both Mandarin and Indonesian, consistent with legal requirements. Communication onboard was a mix of Mandarin, some English, and Indonesian, supporting workflow and coordination.
The captain, Tsai Fu-ching, was a veteran of the industry, known for adherence to routine. The Indonesian crew members were recruited through a licensed agency and had prior experience working on similar vessels. Their diverse backgrounds underscored the transnational nature of the High Aim 6's operations.
Final Voyage of High Aim 6
High Aim 6 was a Taiwanese fishing vessel that vanished under mysterious circumstances. Its disappearance, the fate of its crew, and the unexplained details of its last voyage have drawn attention from investigators and maritime observers alike.
Departure and Intended Route
High Aim 6 departed from the port of Liuchiu, located in southern Taiwan, on October 31, 2002. On board were a Taiwanese captain, Chen Tai-chen, chief engineer Lee Ah-Duey, and a group of Indonesian crew members. The vessel’s initial plan was to set sail for fishing grounds in the vicinity of Indonesia.
According to records, the ship made port in Indonesia on November 16, where it took on additional Indonesian crew. The intended route was typical for Taiwanese tuna longliners, which commonly operate around the Arafura Sea and other waters near Indonesia and Australia. The journey was expected to last several months, with periodic port calls for resupply and to offload catch.
Cargo and Purpose
The High Aim 6 was primarily outfitted for tuna fishing. The onboard equipment included longline gear suitable for targeting large pelagic species, particularly tuna, which is a valuable commodity in international seafood markets.
The purpose of this voyage was commercial fishing. It was not carrying significant cargo aside from standard fishing supplies and provisions for the crew. Freezer units and cold storage indicated that the crew planned to remain at sea for an extended period, maximizing the value of their tuna catch before returning to port. Routine procedures included collecting, processing, and storing caught fish onboard.
Last Known Contact
The final confirmed radio contact with the High Aim 6 took place on December 13, 2002. After this date, there were no further communications from the vessel or any of its crew members. Efforts to reach the crew via standard communication channels were unsuccessful.
Maritime authorities noted that the ship’s emergency beacons and radio appeared to remain functional for some time after the last contact. Later, the vessel was found adrift off the coast of Australia with all crew missing and no clear evidence as to what caused their disappearance. The ship's logbooks and fishing gear remained intact, deepening the mystery.
Discovery and Condition of the Abandoned Vessel
High Aim 6 was discovered adrift with no crew on board, drawing international attention for its mysterious circumstances. Details about where the vessel was found and its condition on discovery provided significant clues for investigators.
Location Where Found
The High Aim 6 was found drifting on January 9, 2003, near Rowley Shoals, off the northwestern coast of Australia. This location is roughly 180 nautical miles west of Broome, in the Indian Ocean, far from its home port in Taiwan.
Australian authorities were notified when a local fishing vessel spotted the abandoned ship. The area is known for its remote reef systems and is not commonly traversed by Taiwanese fishing boats. The ship was eventually towed to Quarantine Bay near Broome for further investigation.
The wide gap between the ship’s expected route and where it was located increased the mystery. Its discovery in Australian waters, far from the Pacific routes typically used by similar vessels, raised questions about what happened during its final voyage.
State of the Ship
Investigators boarding the High Aim 6 found the vessel largely intact and seaworthy. The engine was in working condition, and there was an ample supply of fuel. Essential equipment, including navigational tools and fishing gear, remained on board.
Personal belongings of the crew, such as clothes and food, were left behind, undisturbed. The catch from the ship’s fishing operations was still stored in the hold. There were no immediate signs of struggle, piracy, or distress recorded in the vessel’s logbooks.
The term ghost ship was quickly applied, as the ship appeared perfectly functional but with no trace of its captain or crew. The lack of evidence on board deepened the puzzling nature of the High Aim 6’s abandonment along the remote West Australian coast.
Investigation into the Disappearance
Authorities from multiple countries took swift action after the High Aim 6 was discovered adrift with no crew. Key agencies, including the Australian Federal Police, led a wide-ranging investigation and coordinated search efforts.
Initial Response by Authorities
When the High Aim 6 was found abandoned off the coast of Australia in January 2003, authorities immediately suspected foul play due to the absence of its entire crew and the ship’s operational condition. The Taiwanese owner could not reach the captain or crew, raising alarms of a possible crime. The Australian Federal Police quickly boarded the vessel to conduct a detailed examination.
Investigators found personal items and crew documents still aboard, but no evidence of a struggle. The fishing boat’s logbooks, navigation equipment, and engine were intact and functional. Forensic specialists collected fingerprints and DNA for analysis. Officials from Taiwan and Indonesia were also notified, as most of the crew were Indonesian nationals.
Search and Rescue Operations
Australian authorities, with support from their Taiwanese and Indonesian counterparts, initiated an extensive air and sea search over approximately 24,000 square kilometers. Aircraft and ships systematically scanned the region where the vessel was discovered. Spotters looked for lifeboats, debris, or any sign of the missing crew.
Despite their efforts, neither the captain nor any crew members were found. No distress signals had been received, and weather reports showed no unusual conditions at the time of disappearance. The High Aim 6 remained moored in Australia as evidence while the search and investigation continued.
Theories and Suspicions
Investigators have explored several leading explanations to account for the mysterious disappearance of the High Aim 6’s crew. Attention has focused on potential criminal involvement, vessel control technology, and what might have happened on board before the ship was found adrift.
Foul Play and Possible Motives
Foul play was immediately suspected due to several oddities. The fishing vessel was discovered in Australian waters in January 2003, fully operational and loaded with catch, yet entirely abandoned.
Authorities noted that personal belongings, passports, and food were left untouched. This suggested a sudden and unexpected evacuation. The disappearance puzzled police, as there was no distress call or evidence of a violent struggle.

One leading theory was that a mutiny occurred, possibly involving crew members from Indonesia, as an Indonesian flag was later found on board. Disagreements over pay, working conditions, or illegal activity might have motivated such an incident.
Hijacking Hypothesis
Another suspicion was that the High Aim 6 had been hijacked. Some investigators believed the ship could have been seized by pirates, a real risk in Southeast Asian waters.
Supporting this idea, the vessel was found far off course from its typical routes. The initial theories even included possible human trafficking or smuggling operations. The hypothesis gained traction because the lifeboats were missing, and early suspicions suggested the crew had left intentionally, potentially under duress.
Authorities explored connections with organized crime or piracy rings but found no definitive evidence linking the disappearance to established groups. The lack of communication from the crew added to the uncertainty about whether the hijacking was successful or even occurred.
Autopilot and Vessel Drift
The High Aim 6 was discovered drifting under autopilot, indicating the main machinery was never turned off. This suggested the abandonment was carefully orchestrated or the vessel had been deserted while underway.
Technical analysis showed the ship could have traveled hundreds of kilometers without crew intervention due to the autopilot system. The sustainable operation of the engine and navigation controls supported the theory that the crew had planned to leave or were forced to leave after setting the vessel to maintain course.
Investigators were left to determine if the autopilot enabled planned escape or was merely a byproduct of an emergency. The operation of the autopilot—and the absence of mechanical failure—distinguished this case from routine maritime accidents.
International Context and Similar Cases
Events like the disappearance of the High Aim 6 crew are not isolated in maritime history. Several other ships, sometimes referred to as "ghost ships," have been found adrift with missing or deceased crew under unexplained or mysterious circumstances.
Comparisons to Ghost Ship Incidents
The High Aim 6 is part of a broader pattern involving vessels discovered deserted at sea, often with no clear answers about the fate of those onboard.
These so-called "ghost ship" cases draw attention due to puzzling details—vital safety equipment remains untouched, and logbooks end abruptly. The Taiwanese fishing boat was found adrift with all systems apparently functional, paralleling several such incidents.
Authorities often struggle to determine whether events like mutiny, piracy, or accidental abandonment are involved. Investigations can be hampered by the loss of physical evidence due to ocean conditions or the passage of time.
These mysterious abandonments highlight persistent risks in commercial and private maritime operations. They also emphasize the limitations of maritime search and investigation capabilities, leaving many questions unanswered.
Notable Parallels: MV Joyita and Kaz II
Two notable comparisons are the MV Joyita and the Kaz II. The MV Joyita, a merchant vessel, was found drifting near Fiji in 1955 with all 25 passengers and crew missing, personal belongings left behind, and life rafts unaccounted for.
The Kaz II, a catamaran discovered off the coast of Australia in 2007, also had no sign of its crew. Meals were set on the table, the engine was running, and navigation equipment was intact. Like with High Aim 6, speculation about foul play, accidents, or sudden emergencies circulated but led nowhere definitive.
Ship Name Year Location Final Status MV Joyita 1955 South Pacific Drifting, no crew Kaz II 2007 Australia Drifting, no crew High Aim 6 2003 Australia Drifting, no crew
Each case remains unresolved, reflecting a broader challenge in solving disappearances at sea.
Historic Precedents: Mary Celeste
The disappearance of the crew from the Mary Celeste in 1872 is the oldest and most cited case of a ghost ship. The American merchant brigantine was found in the Atlantic Ocean, seaworthy and fully provisioned, with no one on board.
No definitive explanation has ever been agreed upon for the absence of her captain and crew. Theories include piracy, mutiny, and accidental abandonment, but no proof supports any single cause.
The Mary Celeste set a template for how ghost ship stories are received by the public: with fascination, speculation, and enduring mystery. It remains a benchmark for mysterious maritime events, continually referenced in reports of more recent abandoned ships, such as the High Aim 6.
Geographical Scope and Maritime Context
The High Aim 6 traversed an expansive area that included both the Pacific and Indian Oceans. Its routes brought it into contact with a variety of maritime environments and several significant regional hubs.
Operating Regions in the Pacific and Indian Oceans
The High Aim 6 was primarily a Taiwanese fishing vessel, often operating in international waters between the Pacific and Indian Oceans. Its journey began in southern Taiwan, a frequent departure point for ships engaged in long-line and tuna fishing.
After leaving Taiwan, the vessel sailed toward Indonesia, highlighting the importance of Southeast Asian waters in its operations. These routes frequently passed near the Marshall Islands in the Pacific.
Fishing boats like the High Aim 6 commonly followed seasonal migratory fish stocks, which took them deep into both oceans. The ship did not travel into the Atlantic or Atlantic Ocean, focusing strictly on the East Asian and Australasian maritime regions.
Significance of the West Australian Coast
The West Australian coast became critical to the High Aim 6 incident when the abandoned ship was discovered drifting off the coast near Broome. This stretch of coastline is large, relatively isolated, and exposed to major trade and fishing routes in the eastern Indian Ocean.
Vessels fishing or transiting these waters must contend with strong currents, unpredictable weather, and sparse maritime traffic. Western Australia's remoteness complicates search-and-rescue operations, often delaying incident response and evidence gathering.
Authorities in Western Australia became the central point for investigation, as their resources and jurisdiction covered the immediate area. The proximity to Southeast Asia, especially Indonesia, made this region a significant convergence point for international fishing vessels.
Role of Regional Ports
Ports in southern Taiwan and northern Indonesia served as critical waypoints for the High Aim 6, both for logistics and crew changes. The vessel departed from Liuchiu, a small island port in Taiwan, indicating its linkage to established fishing supply chains.
Indonesian ports—spanning from Aceh to Surabaya—were used for recruiting additional crew members. These ports are accustomed to multinational fishing activity due to their proximity to productive waters.
While the ship was found near Australia, it had not docked at any Australian port. Surrounding regional ports in the Indian and Pacific oceans played essential roles for refueling, resupplying, and manning ships like the High Aim 6, highlighting their strategic value in the region's commercial maritime activity.
Ongoing Mysteries and Open Questions
The High Aim 6 incident raises persistent mysteries that continue to confound investigators and maritime experts. Multiple theories have been proposed, but key facts about the disappearance and the fate of the crew remain unresolved.
Unanswered Questions About the Crew
The most perplexing issue is the disappearance of all crew members. The vessel was found adrift with personal belongings, equipment, and food supplies undisturbed, yet there were no signs of a struggle or distress call.
Speculation spans from mutiny and foul play to abandonment in liferafts. The captain and chief engineer's fate is unknown, and with only one crew member ever located—who reportedly gave conflicting stories—the true sequence of events is elusive.
Rumors of illegal activity, such as smuggling or trafficking, occasionally surface. However, concrete evidence supporting these claims has not been found, leaving law enforcement and families without answers.
Key Unanswered Crew Questions:
Key Point Details Number of crew found 1 (survived, but unverified account) Personal effects on board Present (suggests rapid or forced disappearance) Evidence of distress/piracy None conclusively established
