Caponnetto Hueber has developed an innovative foldable hydrofoil architecture designed to address the most critical practical limitations faced by foiling yachts currently in operation. The system enables larger span foils while allowing full retraction both for harbour operations and sailing scenarios requiring reduced draft or enhanced safety. The solution is currently patent pending.

The Challenge

Conventional foiling systems are limited by vessel beam constraints and suffer from operational challenges related to fouling, cleaning, maintenance and draft limitations in shallow or confined waters.

Our Approach

Caponnetto Hueber dedicated substantial R&D resources to rethinking foil deployment architectures and created a foldable system capable of increasing foil span beyond traditional beam boundaries, while enabling full, safe and controlled retraction.

Results & Impact

The new patent pending foldable foil configuration enables improved performance, extended autonomy, and operational flexibility. It enhances usability in real-world scenarios, from harbour conditions to heavy weather safety modes.

What It Means

This approach de-risks the adoption of foiling across a wider range of vessel categories, making high-performance hydrofoil technology more accessible, more efficient and more practical for everyday maritime use.

Standards and Harmonisation

The development intends to align with future regulation for retractable appendages, and supports scalability for both electric and combustion propulsion configurations, enabling reduced emissions and more energy efficient marine mobility.

Conclusion

This foldable hydrofoil system eliminates key barriers that have so far limited foiling in broader market adoption, opening a path towards safer, more flexible and more sustainable hydrofoil-enabled craft.

Always searching for new concepts and practical efficient solutions, significant R & D resources are spent by our team of engineers to improve our current solutions and systems.

In this context, CH has developed a solution which solve the main drawbacks of foiling crafts currently in operation

CH has developed an innovative Foldable Hydrofoil System (patent pending) that include many advantages for a foiling yacht

  • Advantages:
  • Larger foil span
    • for improved performance and autonomy
    • no more constraints on maximum foil span being smaller than maximum beam of the yacht or vessel
  • Full retraction system:
    • in harbor, at mooring or when not operating:
      • To avoid fouling and for easy cleaning
      • For easy maintenance
    • In operation:
      • To reduce the total draft in shallow water
      • For safety reasons, in heavy weather or big waves

This innovative system can be used with electric propulsion to increase the performance, range or autonomy or adapted to combustion propulsion, decreasing the fuel consumption and the emissions.

The system enables to solve most of practical concerns of the foiling configurations and solutions currently available on the market.
