Record attempt: Sedlacek fails for the sixth time. Update

From the official statement: “​BIt’s been brilliant so far – a really good and impressive start … But you have to accept that you can’t control everything. The sailor and the team are left behind with heavy hearts – the ANT ARCTIC LAB is now over. Norbert is currently on his way back to Les Sables.... Following serious problems with all the navigation electronics and electrical systems, Norbert was forced to turn back yesterday at 15:45 UTC. At present, only the emergency systems are still functioning. The hull and rigging are undamaged, and the most essential communication links are operational. He is able to navigate safely and is expected to arrive in Les Sables sometime next week.”

Austrian sailor Norbert Sedlacek is aiming, with the ANT ARCTIC LAB project, to sail non-stop and single-handed around the world across all five oceans. The planned route runs from Les Sables-d’Olonne (the starting port of the Vendée Globe) to the Arctic, round Spitsbergen, on to Antarctica and back to France. The project also serves as an extreme test for a sustainable, largely recyclable Open 60 yacht.

Chronology of Norbert Sedlacek’s experiments

Norbert Sedlacek’s six attempts did not fail due to a single, recurring fault. The problems lay in different areas in each instance:

• Power supply and electronics: 2018 and 2021 respectively
• Sails and deck equipment: 2019
• Steering system: 2022
• Swivel or tilting keel: 2023
• Unresolved termination: 2026

What these experiments have in common is that the problems occurred in European waters or shortly afterwards. Sedlacek has not yet undertaken any expeditions to the remote southern oceans.

Reasons for the repeated terminations

1. An experimental vessel that is extremely technically sophisticated

The “Innovation Yachts” was not built as a conventional yacht, but as a test vessel. It is designed both to enable a non-stop circumnavigation of the globe and to demonstrate the durability of vulcanised fibres, recyclable composite materials, sustainable resins and electrical systems. This meant that several new or unusual technologies were deployed simultaneously under extreme conditions.

2. The length and difficulty of the planned route

The route covers around 32,000 nautical miles and about half a year at sea on its own. It will sail through the Arctic and the Southern Ocean – regions where repairs are virtually impossible. From the perspective of Norbert Sedlacek’s team, it therefore makes more sense to turn back at the first sign of a safety-critical fault, rather than risking the boat’s safety later on, far from any help.

3. A development project, not just an attempt to break a record

Sedlacek explicitly regards ANT ARCTIC LAB as an ongoing development process. After each failure, the affected components were analysed, redesigned and reinforced. In an interview with YACHT, he explained, in essence, that there was no point in setting out on a 35,000- to 40,000-nautical-mile voyage with a power supply that did not function reliably or a damaged system. The aim is not to lose the boat in spectacular fashion, but to prove that the concept works in the long term.

An analysis of Norbert Sedlacek’s sixth failure

At the sixth attempt in 2026 The evidence is considerably more scant than in the case of the earlier terminations. All that is known is:

• The launch took place on 26 July 2026 in Les Sables-d’Olonne.
• Sedlacek turned back on the first leg of his journey towards Spitsbergen, off the coast of Iceland.
• The team wrapped up the project with a cryptic message.
• No specific damage, component or medical reason has been mentioned so far.

The only thing that can be said with certainty at this stage is that this attempt, too, was abandoned before the actual high-risk areas were reached. The sixth attempt thus forms part of a series in which technical reliability and the limitations of an experimental boat design were the decisive factors.

Book recommendations

Alone against the wind – non-stop round the world in 343 days describes Wilfried Erdmann’s single-handed, non-stop circumnavigation of the globe against prevailing winds and currents. The focus is on storms, solitude, limited resources and the psychological strain of a voyage lasting several months. For the article on Norbert Sedlacek, this first-hand account provides a vivid insight into the demands and risks of such a long-distance sailing project.

Yacht accidents focuses more closely on the causes of specific accidents. Topics covered include the loss of rudders and keels, collisions, heavy seas, groundings, emergency communications and human error. The book thus complements the personal account of the expedition with an objective analysis from a safety engineering perspective. Readers will be better able to assess technical failures and operational decisions in extreme sailing projects.
