ACCWing 100% Composite – The Smart Rigid Wing for Workboats and Sailing Drones

ACCWing Composite is a next-generation rigid wing designed for wind propulsion of workboats and autonomous marine drones. Made entirely from flexible composite materials, it features a textile-free composite structure that ensures high durability, enhanced resistance to marine environments, and consistent aerodynamic performance.

Equipped with composite panels and internal actuators, the wing features automatically controlled variable camber. Its architecture allows for dynamic adaptation to wind conditions, with lift forces reaching up to twice that of a conventional rig of the same surface area.

Robust, reefable, furlable, low-maintenance, and operable without a crew, ACCWing Composite is a reliable, intelligent wind propulsion solution perfectly suited to new generations of maritime platforms—whether professional or autonomous.

The wing can be installed on either a stayed or freestanding mast, with a balanced geometry around its rotation axis. This configuration minimizes mechanical loads, reduces energy requirements for control, and simplifies integration on existing hulls, even lightweight ones.

Thanks to its aerodynamic efficiency and low drag, ACCWing Composite enables effective sailing up to 25° off the true wind, delivering strong upwind performance—even for drones or autonomous vessels operating over long distances.

For long-endurance autonomous system applications (drones), the wing is non-retractable and remains permanently in an upright position, continuously self-regulating without human intervention. Camber, angle of attack, and rotation around the mast are fully automated through an onboard control system capable of responding to the environment and navigation strategy in real time and proactively.
