Stability Meets Efficiency
The Autark Zero is designed as a catamaran (LOA 12m, beam 4m), which has better stability compared to monohull vessels. Additionally, because of its low drag, this vessel optimises hydrodynamic performance and significantly reduces energy consumption for propulsion, maximising the efficiency of its wind and solar power systems.
One of the most remarkable features of the Autark Zero is its shallow draft of just 0.5 metres. This is achieved through a combination of several design elements:
- Retractable Daggerboards: These movable underwater foils can be raised or lowered as needed, allowing the vessel to navigate in extremely shallow waters.
- Retractable Rudders: The steering system can be lifted to reduce draft further when necessary.
- Electric Pod Motors/Thrusters: These compact, retractable propulsion units contribute to the shallow draft while providing efficient and quiet propulsion. Furthermore these thrusters can rotate 180 degrees making thrust vector steering possible for precise manoeuvring.
Even though the vessel is a prototype and is not currently aiming at seaworthiness to cross the oceans, it is notable to mention that thanks to the shallow draft and retractable thrusters the Autark-Zero can access waterways that are off-limits to traditional boats, such as lagoons and shallow bays, even drying out on a sandbank is possible. The length and beam of the boat are such that also European marinas and narrow canals in France and England can be navigated.
Construction
The Autark Zero prototype uses a woodcore sandwich construction method, enabling rapid, cost-efficient prototyping without expensive moulds. While the prototype uses woodcore, future production models will shift to composite construction for improved performance and weight reduction. Throughout its development, the Autark Zero incorporates bio-composites, sustainable timber, and bio-fibers in its production process, setting the stage for more sustainable practices in yacht manufacturing.
